In legacy method, 1st stage bootloader was used to configure the HW

This commit is to add config option
CONFIG_NAND_ZYNQ_USE_BOOTLOADER1_TIMINGS that allow NAND driver use
timing values set by the 1st stage bootloader, instead of the hard-coded

mx6sxsabresd can run different kernel versions, such as NXP 4.1 or mainline.

Currently the rootfs location is passed via mmcblk number and the
problem with this approach is that the mmcblk number for the SD
card changes depending on the kernel version.

In order to avoid such issue, use the UUID method to specify the
rootfs location.

The boot (and fallback/emergency boot) concept for the RK3399-Q7
differs from Rockchip's reference platforms.

On the RK3399-Q7, some of this functionality is present in the
bootloader itself (and configurable); some is backed in hardware by
the Qseven BIOS_DISABLE signal to invoke the final stages of fallbacks
(i.e. either an external boot bypassing on-module memories or falling
back to the BROM for USB recovery).

In summary: the ADC-based boot_mode check does not apply for the
RK3399-Q7 and we therefore disable it (in this commit) by setting
CONFIG_BOOT_MODE_REG to 0.
Signed-off-by: NPhilipp Tomsich <philipp.tomsich@theobroma-systems.com>

The ROCKCHIP_BOOT_MODE_REG option defaults to a hex value, so 0 will
show as 0x0 if a default is provided and changed via Kconfig.
However, it still will show as 0, if no default is given.

Consequently, the "is set to something other than 0" test in a
Makefile is cumbersome.  Instead this check can easily be performed in
the C-code.

This removes the ifeq-check from mach-rockchip/Makefile, adds a
matching #if-check to boot_mode.c and fixes resulting link issues (if
boot_mode.o was not included due to the Makefile check) by defining a
stub function (in case the functionality is not built in) for
setup_boot_mode in boot_mode.c.

The RK3399 has a total of 9 I2C controllers.  To support these, the
enum in periph.h is extended and the mapping from the IRQ numbers to
the peripheral-ids is extended to ensure that pinctrl requests are
passed through to the function configuring the I2C pins.

For I2C8, the pinctrl is implemented and tested (on a RK3399-Q7) using
communication with the FAN53555 connected on I2C8.

The RK3399 clk driver still has a left-over use of extract_bits, which

A minor code-size increase from the changes for tracking the os-type
of FIT images and from infrastructure for recording the loadables into
the the loaded FDT, broke the builds for sun50i and some OMAP2+ devices.

This change adds a new config option (enabled by default for
MACH_SUN50I, MACH_SUN50I_H5 and ARCH_OMAP2PLUS) that does skips these
processing steps (bringing code size down to below the limit
again). The os-type is not evaluated, but assumed to be IH_OS_UBOOT
(i.e. taking the code-paths intended for backward-compatibility).

Note that enabling this config option precludes any useful downstream
processing, such as utilising a special calling convention for ATF or
OPTEE, based on the os-type of the loadables.
