usb: typec: mux: intel_pmc_mux: Add retry logic to a PMC command

There are few scenerio when PMC reports 'busy condition' and command
fail.

If PMC receives a high priority command while servicing a low priority
command then it discards the low priority command and start servicing
the high priority command. The lower priority command fail and driver
returns error. If the same command resend to the PMC then PMC latches
the command and service it accordingly.

Thus adds the retry logic for the PMC command.
