Use the same SPL_STACK_R_ADDR in Kconfig instead of each board config;
default to 0x4000000(64MB) instead of 0x80000(512KB) for this address
can support all the SoCs including those may have only 64MB memory, and
also reserve enough space for atf, kernel(in falcon mode) loading.
After the ATF entry move to 0x40000, the stack from 0x80000 may be override
when loading ATF bl31.

We use to reserve IRAM to avoid the SPL text overlap with ATF M0 code,
and when we introduce the TPL, the SPL space is in DRAM, we reserve
space to avoid SPL text overlap with ATF bl31.
Now we decide to move ATF entry point to 0x40000 instead of 0x1000,
so that the SPL can have 0x4000 as code size and no need to reserve
space or relocate before loading ATF.
The mainline ATF has update since:
