rockchip: rk3368: fix PLAT_RK_CLST_TO_CPUID_SHIFT
The RK3368 has two clusters of 4 cores and it's cluster id starts at bit 8 of the MPIDR. To convert from the cluster id (0 or 1) to the lowest CPU-ID in the respective cluster, we thus need to shift by 6 (i.e. shift by 8 to extract the cluster-id and multiply by 4).
This change is required to ensure the PSCI support can index the per-cpu entry-address array correctly.

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.
