Commit Message

The BCM59054 is fairly similar in terms of regulators to the already
supported BCM59056, as included in the BCM590XX driver.

Add support for the BCM59054's regulators to the BCM590XX driver.
Switch from using defines for common checks to using functions which
return different values depending on the identified MFD model.

While we're at it, fix a bug where the enable/vsel register
offsets for GPLDO and LDO regulators were calculated incorrectly.

Also, change the regulator enable bitmask to cover the entire PMMODE
register.

As is very clear from the commit log this is a whole bunch of changes
which really should be split out into multiple patches.  There's the
bug fix, there's the multiple refactorings to support the new device and
the new device itself.  As covered in submitting-patches.rst you should
do one change per patch, this makes things much easier to follow.

There's no error handling here if there's an unknown type.

It seems like everything would be a lot simpler and clearer to just have
tables of regulators per device rather than have all these conditionals.
