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.
