lib: sbi: Set the scratch allocation to alignment to cacheline size
Set the scratch allocation alignment to cacheline size specified by
riscv,cbom-block-size in the DTS file to avoid two atomic variables
from the same cache line causing livelock on some platforms. If the
cacheline is not specified, we set it a default value.
