regulator: fan53555: Add support for FAN53555BUC23X type

Browse source

FAN53555BUC23X has the ID 0 and REV 0xc, starts at 600mV and
increments in 12.5mV steps.

Per the datasheet, the FAN53555BUC23X (23 option) is grouped with
the 00 and 13 options for soft-start timing (t_SS = 300us typ.),
so the existing enable_time = 400 is reused here as well.

This variant is found on the ASUS Tinker Edge R (RK3399Pro) as the
supply regulator for both vdd_gpu and vdd_cpu_b. Verified across
the full GPU OPP table with the userspace devfreq governor.
