This is only used by omap1.
And to fix things properly, this should not be included
from the drivers at all.

This functionality has already been implemented in the cx20442 codec
driver (commit f75a8ff67d, "ASoC: cx20442:
add bias control over a platform provided regulator"), no need to keep
it here duplicated.
Once done, remove the no longer used AMS_DELTA_LATCH2_MODEM_NRESET
symbol from the board header file and a call to the regulator_toggle()
helper function from the old API wrapper found in the board file. While
being at it, simplify the way the modem .pm callback handles the
regulator and drop that helper function and its related consumer setup
completely.
Depends on patches 1/3 and 2/3 for clean apply and keep things working.

Don't use Amstrad Delta custom I/O functions once GPIO interface is
available for the underlying hardware.
While requesting and initializing GPIO pins used, also take care of one
extra pin KEYBRD_DATAOUT which, even if not used by the driver, belongs
to the device and affects its functioning.
Once done, move the driver initialization back to the device_initcall
level, reverting the temporary chane introduced with patch 1/7 "ARM:
OMAP1: ams-delta: register latch dependent devices later". That change
is no longer required once the driver takes care of registering used
GPIO pins, and it's better to initialize the device before others using
the latch2 based GPIO pins, otherwise a garbage is reported on boot,
perhaps due to random data already captured by the FIQ handler while the
keyboard related latch bits are written with random values during
initialization of those other latch2 dependent devices.

Now that the Amstrad Delta on-board latches have been converted to GPIO
devices, use the generic driver to control on-board LEDs which hang off
those latches.

Once ready, ams-delta specific device drivers currently calling custom
ams_delta_latch[12]_write() functions can be updated to call generic
gpio_set_value() instead, which will make them less platform dependent.
Even more, some custom ams-delta only drivers can perhaps be dropped
from the tree after converting selected ams-delta platform devices to
follow generic GPIO based device models.
The latch_gpios[] table is initially filled with all latch1 and latch2
GPIO pins in order to register and initialize them from the board file
until those are handled by respective existing device drivers (leds,
nand, lcd, serio, asoc, serial). That table will get almost empty after
the transision process is completed, holding only pins not used by any
drivers / connected to unused devices, in order to initialize them from
the board file for power saving purposes.
The new ams_delta_latch_write() function is a unified replacement for
those removed ams_delta_latch[12]_write(), and serves as a temporary
wrapper over gpio_set_value(), providing the old API for those not yet
updated device drivers, and will be removed after all custom drivers are
converted or replaced.
