(lib: Move all coldboot wait APIs to sbi_init.c) caused a regression while moving the code from sbi_hart.c to sbi_init.c. As per original commit text, WFI can be implemented as a NOP according to the RISC-V privilege specification. Software should ensure that relevant interrupt pending bits are set. Otherwise, loop back to WFI. Fix the regression by applying the original patch to sbi_init.c. Fixes:71d2b837c4
