According to PSCI specification v1.0, the PSCI functions should start from 0x84000000 for SMC32, this patch changes this base value as well as other function offset values.
Out of curiosity: Do you plan to ever support ARMv8 boards with PSCI services in U-Boot as well? Then we would need to think about adjusting the function IDs, because they use a "64-bit" flag for some functions.
