Andrey Smirnov 5df884d4b8 tty: serial: fsl_lpuart: Fix lpuart_flush_buffer() 
Fix incorrect read-modify-write sequence in lpuart_flush_buffer() that
was reading from UARTPFIFO and writing to UARTCFIFO instead of
operating solely on the latter.

Fixes: 9bc19af9da ("tty: serial: fsl_lpuart: Flush HW FIFOs in .flush_buffer")
