rockchip: Update BL31_BASE to 0x40000 

Rockchip platform is using the first 1MB of DRAM as secure ram space,
and there is a vendor loader who loads and runs the BL31/BL32/BL33,
this loader is usually load by SoC BootRom to the start addres of DRAM,
we need to reserve enough space for this loader so that it doesn't need
to do the relocate when loading the BL31. eg.
We use U-Boot SPL to load ATF BL31 and U-Boot proper as BL33, the SPL
TEXT BASE is offset 0 of DRAM which is decide by Bootrom; if we update
the BL31_BASE to offset 0x40000(256KB), then the 0~0x40000 should be
enough for SPL and no need to do the relocate while the space size
0x10000(64KB) may not enough for SPL.
After this update, the BL31 can use the rest 768KB of the first 1MB,
which is also enough, and the loader who is using BL31 elf file can
support this update without any change.
