8250: microchip: pci1xxxx: Add workaround for RTS bit toggle
[ Upstream commit e95cb63e57381f00d9274533ea7fd0ac3bf4e5b0 ]
In the B0 revision, the RTS pin remains high due to incorrect hardware
mapping. To address this issue, enable auto-direction control with the
RTS bit in ADCL_CFG_REG. This configuration ensures that the RTS pin
goes low when the terminal is opened and high when the terminal is
closed. Additionally, we reset the step counter for Rx and Tx engines
by writing into FRAC_DIV_CFG_REG.
