Adds pinconf support for the Amlogic pinctrl driver (fixed)

Adding pinconf support is necessary to enable boot from SPI
without breaking the eMMC. When booting from SPI, the ROM code
leave pull downs on the eMMC pad.

We need to set pinconf provided in DT to solve this

Make use of "IMAGE_MAX_SIZE" and "IMAGE_TEXT_BASE" rather than
CONFIG_SPL_MAX_SIZE and CONFIG_SPL_TEXT_BASE.  This lets us re-use the
same script for both SPL and TPL.  Add logic to scripts/Makefile.spl to
pass in the right value when preprocessing the script.

I'm working on getting OpenBSD to run on the Atmel SAMA5D3 Xplained.
OpenBSD uses an EFI bootloader, which requires the "load" command to
work, since "fatload" doesn't initialize the EFI memory addresses
properly. To get "load" on the SAMA5D3 version of U-Boot, I propose
adding the CONFIG_CMD_FS_GENERIC option.

In case when the environment on some location is malformed (CRC isn't
matching), there is a chance we won't be able to save the environment to
that location. For example, consider the case when we only have the
environment on eMMC, but it's zeroed out. In that case, we won't be able
to "env save" to it, because of "bad CRC" error. That's happening
because in env_load() function we consider malformed environment as
incorrect one, and  defaulting to the location with highest (0)
priority, which can be different from one we are dealing with right now
(e.g., highest priority can be ENV_FAT on SD card, which is not
inserted, but we want to use ENV_MMC on eMMC, where we were booted
from).

This issue began to reproduce after commit d30ba231 ("u-boot: remove
driver lookup loop from env_save()") on BeagleBone Black, but that
commit didn't introduce the wrong logic, it just changed the behavior
for default location to use, merely revealing this issue.

To fix that, let's implement next logic in env_load():
  1. Try to find out correct environment; if found -- use it
  2. If working environment wasn't found, but we found malformed one
     (with bad CRC), let's use it for further "env save". But make sure
     to use malformed environment location with highest priority.
  3. If neither correct nor malformed environment was found, let's
     default to environment location with highest priority (0)

Steps to reproduce mentioned issue on BeagleBone Black (fixed in this
patch):

1. Boot from SD card and erase eMMC in U-Boot shell:
   => mmc dev 1
   => mmc erase 0 100000
   => gpt write mmc 1 $partitions
2. Write new SPL and U-Boot to eMMC; the rest of eMMC will stay filled
   with zeroes
3. Boot from eMMC; try to do:
   => env save
4. Observe the error (incorrect behavior). Correct behavior: environment
   should be stored correctly on eMMC, in spite of it has "bad CRC"

Callers of env_import*() functions might want to check the case when we
have incorrect environment (with bad CRC). For example, when environment
location is being defined in env_load(), call chain may look like this:

    env_load() -> drv->load() = env_mmc_load() -> env_import()

Return code will be passed from env_import() all way up to env_load().
Right now both env_mmc_load() and env_import() return -EIO error code,
so env_load() can't differentiate between two cases:
  1. Driver reports the error, because device is not accessible
  2. Device is actually accessible, but environment is broken

Let's return -ENOMSG in env_import(), so we can distinguish two cases
mentioned above. It will make it possible to continue working with "bad
CRC" environment (like doing "env save"), instead of considering it not
functional (implemented in subsequent patch).

CLI support with the HUSH parser is not currently SPL safe due to it's
use of realloc. That function is not defined for SPLs that use
SYS_MALLOC_SIMPLE. CLI support can be built in to SPL and some functions
do work, but use of some like run_command() will cause build to fail.
When no SPL code calls this function build works as the compiler removes
this unreachable code so the unresolved symbols are ignored.

If DFU support is enabled in SPL then MMU DFU support may get brought in
also, this code does make a call to run_command() causing build to fail
if the HUSH parser is not built-in. To break this odd and unneeded
dependency chain we use CONFIG_IS_ENABLED where appropriate to prevent
calls into HUSH code from SPL. This also removes our need to pull in the
rather unrelated source file when SPL_DFU is defined.

 * Fix with private structure allocation for arc_uart
 * Definition of CONFIG_SYS_CACHELINE_SIZE useful for building drivers

Even though we don't use CONFIG_SYS_CACHELINE_SIZE in ARC-specific code
it is used a lot in different drivers for alignment purposes.

So we define it and make much more drivers at least compilable for ARC.
