A secure monitor that runs before U-Boot, and hence causes U-Boot to run
in non-secure world, must implement a few operations that U-Boot
otherwise implements when running in secure world. Fix U-Boot to skip
these operations when running in non-secure world. In particular:
- The secure monitor must provide the LP0 resume code and own LP0
configuration in order to maintain security, so must initialize all
the PMC scratch registers used by the boot ROM during LP0 resume.
Consequently, U-Boot should not attempt to clear those registers,
since the register accesses will fail or cause an error.
- The secure monitor owns system security, and so is responsible for
configuring security-related items such as the VPR.

There is no need to keep a separate coreboot_fb.dtsi since now we
have a generic coreboot payload dts.
While we are here, this also remove the out-of-date description in

Currently building U-Boot as the coreboot payload requires user
to change the build configuration for a specific board during
menuconfig process. This uses the board's native device tree
to configure the hardware. For example, the device tree provides
PCI address range for the PCI host controller and U-Boot will
re-program all PCI devices' BAR to be within this range. In order
to make sure we don't mess up the hardware, we should guarantee
the range matches what coreboot programs the chipset.
But we really should make the coreboot payload support easier.
Just like EFI payload, we can create a generic coreboot payload
for all x86 boards as well. The payload is configured to include
as many generic drivers as possible. All stuff that touches low
level initialization are not allowed as such is the coreboot's
responsibility. Platform specific drivers (like gpio, spi, etc)
are not included.

There were NULL pointers dereferenced because DM was used
too early without correct initialization:
- malloc_simple returned NULL when called from preloader_console_init()
because gd->malloc_limit was 0
- uclass_add dereferenced gd->uclass_root members which were NULL because
dm_init (or one of its relatives) has not been called.
All this is fixed by calling spl_early_init before calling
preloader_console_init.
