This patch adds SD boot support for LS1021AQDS board. SPL
framework is used. PBL initialize the internal RAM and copy
SPL to it, then SPL initialize DDR using SPD and copy u-boot
from SD card to DDR, finally SPL transfer control to u-boot.

Through adding CONFIG_QIXIS_I2C_ACCESS macro,
QIXIS_READ(reg)/QIXIS_WRITE(reg, value) can be used
for both i2c and ifc access to QIXIS FPGA. This is
more convenient for coding.

On LS1, DDR is initialized by reading SPD through I2C interface
in SPL code. For I2C, ll_entry_count() is called, and it returns
the number of elements of a linker-generated array placed into
subsection of .u_boot_list section specified by _list argument.
So add I2C linker list in the generic .lds to fix the issue about
using I2C in SPL.

In SD boot, the magic number of u-boot image will be checked.
For LS102xA, u-boot.bin doesn't have the magic number. So use
u-boot.img which includes the magic number instead of u-boot.bin
when producing u-boot-with-spl-pbl.bin.

For LS102xA, the size of spl/u-boot-spl.bin is variable.
This patch adds the support to deal with the variable
u-boot size in pblimage tool. It will be padded to 64
byte boundary.

Use pblimage_check_params() to add the specific operations
for ARM, such as PBI CRC and END command and the calculation
of pbl_cmd_initaddr.

Some UniPhier boards are equipped with an expansion slot that
some optional SRAM/NOR-flash cards can be attached to.  So, run-time
detection of the number of flash banks would be more user-friendly.

Until this commit, UniPhier boards have achieved this by (ab)using
board_flash_wp_on() because the boot failed if flash_size got zero.
Fortunately, this problem was solved by commit 70879a92 (flash:
do not fail even if flash_size is zero).

Now it is possible to throw away such a tricky workaround.  This
commit also enables CONFIG_SYS_MAX_FLASH_BANKS_DETECT for further
refactoring.

The boot commands - bootz/bootm mandate a third argument which is the
address to the FDT blob. In cases where this argument is not specified,
boot fails with a message indicating a missing FDT.

This causes non-FDT kernels to fail to boot. This patch allows both FDT
and non-FDT kernels to boot by making the third parameter to the bootm/bootz
optional.

Introduce a Makefile under arch/$ARCH/ and include it in the
top Makefile (similar to Linux kernel). This allows further
refactoringi like moving architecture-specific code out of global
makefiles, deprecating config variables (CPU, CPUDIR, SOC) or
deprecating arch/$ARCH/config.mk.

In contrary to Linux kernel, U-Boot defines the ARCH variable by
Kconfig, thus the arch Makefile can only included conditionally
after the top config.mk.
