[PATCH] riscv: Move all SMP related SBI calls to SBI_v01

Tue Apr 21 23:51:57 CEST 2020
SMP support for S-mode U-Boot is enabled only if SBI_V01 is enabled.
There is no point in supporting SMP related (IPI and fences) SBI calls
when SBI_V02 is enabled.
Modify all the SMP related SBI calls to be defined only for SBI_V01.
