rockchip: bring TZRAM_SIZE values in line

The agreed upon division of early boot locations is 0x40000 for bl31
to leave enough room for u-boot-spl and 0x100000 for bl33 (u-boot).

rk3288 and rk3399 already correctly secure the ddr up to the 1MB boundary
so pull the other platforms along to also give the Rockchip TF-A enough
room to comfortably live in.
