serial: 8250_dw: build Renesas RZN1 CPR value from DW_UART_CPR_* definitions
Replace the magic CPR value for Renesas RZ/N1 with a composition using
DW_UART_CPR_* bit/field definitions and FIELD_PREP_CONST().
Introduce a helper macro to convert a FIFO size (bytes) into the CPR
FIFO_MODE field value, with BUILD_BUG_ON_ZERO() checks for alignment and
bounds. Use it to replace the literal FIFO_MODE values in the RZN1.
