serial: 8250: Add Loongson uart driver support
Add the driver for on-chip UART used on Loongson family chips.
The hardware is similar to NS16550A, but there are the following
differences:
- Some chips (such as Loongson-2K2000) have added a fractional division
register to obtain the required baud rate accurately, so the
{get,set}_divisor callback is overridden.
- Due to hardware defects, quirk handling is required for
UART_MCR/UART_MSR.
