drivers: serial: ns16550: add automatic DLF calculation ...
The static 'dlf' property is valid only for a specific PCLK/baud rate
combination. The current calculation accounts for this fixed value when
selecting the integer divisor, but cannot adapt to runtime baud rate
changes.
A low fixed PCLK may require a fractional divisor to reduce baud rate
error for the requested baudrate.
Add an opt-in 'dlf-auto' property to calculate the integer divisor and
DLF value together whenever the baud rate changes, using 1/64-resolution
fixed-point arithmetic. When enabled, 'dlf-auto' overrides 'dlf'.
Also enable DLF support when an instance uses either 'dlf' or
'dlf-auto'. Existing 'dlf' users are unaffected.
