TPL max size is limited to 184 KB, SPL is loaded to 0x0 and TF-A is
loaded to 0x40000, this limit SPL max size to 256 KB. With BootRom only
reading first 2 KB per 4 KB page of SPI flash, 880 KB may be needed for
TPL+SPL in a worst-case scenario. (184 KB + 256 KB) x 2 = 880 KB
Use 0xE0000 (896 KB) as the payload offset in SPI flash, this allows
for a payload of 3168 KB before env offset start to overlap.
Also add CONFIG_ROCKCHIP_SPI_IMAGE=y to build a bootable SPI flash
image, u-boot-rockchip-spi.bin.

Long are gone the times TF-A couldn't handle the FDT passed by U-Boot.
Specifically, since commit e7b586987c0a ("rockchip: don't crash if we
get an FDT we can't parse") in TF-A, failure to parse the FDT will use
the fallback mechanism. This patch was merged in TF-A v2.4-rc0 from two
years ago.
New boards should likely have this option disabled or explicitly enable
it in their respective defconfig.
Because existing boards might depend on a TF-A version that predates
v2.4, let's just enable this option in all RK3399 defconfigs.
Maintainers of each board can decide for themselves if they would prefer
to disable this option and allow U-Boot to pass the DT to TF-A.

Add the RAM_ROCKCHIP_LPDDR4 to fix the Pinephone Pro booting.
When the configs were updated in 26f92be07e it somehow broke
the PPP boot process so let's fix it.
