gas: update csect alignment for PPC prefixed instructions on XCOFF
Power10 prefixed instructions must not cross 64-byte boundaries.
This is already handled.
However, on XCOFF, the csect must be updated to match the new
alignment.
* config/tc-ppc.c (md_assemble): Update ppc_current_csect
alignment when finding prefixed instructions.
