drivers/clocksource is missing in master repository and as far I know we are
made patches for "master" but not for "next".

This is constant frequencies and it is used only here. Is this really need?

Base address is not needed because it is impossible to request resource for
registers for this CPU. Registers is shared for all devices.

Simple check is provided in serial driver by definition, for example:
SYSFLG(x) ? SYSFLG2 : SYSFLG1, where x is "id".
But, you are right, I will made one more check for id in "probe".
