Driver: Hsuart: set the rfr pin  atomic operation

BUG: 145473663

The RFR signal set to deactive and the RX_RDY_CTL set to disable during
runtime sleep. The RFR signal set to  deactive and RX_RDY_CTL set to
enable during runtime resume.
If schedule happed during the two operation enable/disable RX_RDY_CTL
and set/reset RFR, The Rx FIFO may be overrun. So The two operation
should be atomic
