Aaron Sierra a816a7e1e7 serial: 8250: Preserve DLD[7:4] for PORT_XR17V35X
[ Upstream commit 0ab84da2e0 ]

The upper four bits of the XR17V35x fractional divisor register (DLD)
control general chip function (RS-485 direction pin polarity, multidrop
mode, XON/XOFF parity check, and fast IR mode). Don't allow these bits
to be clobbered when setting the baudrate.
