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.

Just a nitpick/question (and for the whole series): Is there any
specific reason for going back to the Kconfig way
(CONFIG_SYS_SPI_U_BOOT_OFFS) instead of just modifying the offset in the
-u-boot DTSI?
On a different note, that also means that we're effectively breaking
current setups by moving the environment some other location. I cannot
talk for the maintainer(s) and user(s) but I thought it was worth
mentioning.

nitpick: We *could* have this in another commit after we move the
environment to another location later in the SPI flash.
