broadwell: add RCBA posting read after writing
MEI PCI device has internal logic to flush out the posted writes
before returning completion for non-posted request. When doing a RCBA
write to function disable and then using the PCI CFG RD cycle, need
to do RCBA posting read after writing to it to make sure the write
went through.
As Aaron sugegsted, abstracted function disable path to a common
function.
