drivers/pc80/rtc/mc146818rtc.c: Add Kconfig for RTC CMOS base addresses

Configure the CMOS bank I/O base addresses with
PC_CMOS_BASE_PORT_BANK* rather than hard-coding as 0x70, 0x72.  The
defaults remain the same.

Librem Mini v1/v2 has an automatic power-on setting provided by the EC
that can be configured in its BRAM bank 1.  The RTC uses the PCH CMOS,
and it is preferable not to change this in an update, as the RTC would
reset.  By configuring these addresses, we can use the PCH CMOS bank 0
and the EC BRAM bank 1.
