Add support for the ROHM BD73800 PMIC and compatibles.

The ROHM BD73800 is a power management IC which integrates 8 BUCKs and 4
LDOs. There is also an ADC and operation amplifier intended for current
/ temperature measurement and accumulation. RTC and 32.768 kHz clock
gate are also included. The PMIC can be customized via OTP and it has
options for operating as a main PMIC in multi-PMIC installation. Some
of the pins can also be used for GPO or GPI (including interrupt support).

There are also ROHM BD71851 and BD71885 PMICs out there. These are, from
the SW-perspective, similar to the BD73800. There is only some different
default values and OTP settings. The driver should be able to handle them
just fine.

Oh, finally - there is absolutely no rush reviewing this. I am likely to
be (mostly) offline for (at least) 3 weeks. So please, take your time, I
probably will spin the next version only somewhere at August.
