MN10300: Introduce barriers to replace removed volatiles in gdbstub 16550 driver

Introduce into the MN10300 gdbstub 16550 driver a couple of barrier() calls to
replace the removed volatility of the input/output index variables for the Rx
ring buffer.  A previous patch added them into the on-chip serial port driver.
