rockchip: rk3399-gru: Move SPI flash payload offset for bob and kevin

The BootROM on RK3399 only read the first 2 KB of each 4 KB page from
SPI flash. With current FIT payload offset of 0x40000 this limits the
supported TPL+SPL size to only 128 KB.

Change to use 0xE0000 as FIT payload offset, similar to other RK3399
boards, to allow a maximum size for TPL of 192 KB and SPL of 256 KB.
