regulator: lochnagar: Add on_off_delay for VDDCORE
The VDDCORE regulator takes a good length of time to discharge down, so
add an on_off_delay to ensure DCVDD is removed before it is powered on
again.

regulator: lochnagar: Fix n_voltages setting for VDDCORE
With current n_voltages setting, regulator_list_voltage will return
-EINVAL when selector >=57. The highest selector is 0x41, so the
n_voltages should be 0x41+1, i.e. 66.

regulator: lochnagar: Explicitly include register headers
Review of the MFD component has stated we should not include the
register headers through lochnagar.h and thus removed them from that
header. Explicitly include them in the end drivers manually.

regulator: lochnagar: Add support for the Cirrus Logic Lochnagar
Lochnagar is an evaluation and development board for Cirrus
Logic Smart CODEC and Amp devices. It allows the connection of
most Cirrus Logic devices on mini-cards, as well as allowing
connection of various application processor systems to provide a
full evaluation platform. This driver supports the board
controller chip on the Lochnagar board.

The Lochnagar board provides power supplies for the attached
CODEC/Amp device. Currently this driver supports the microphone
supplies and the digital core voltage for the attached
device. There are some additional supplies that will be
added in time but these supplies are sufficient for most
systems/use-cases.
