Now that a regulator device for controlling the codec chip reset state
over a platform agnostic regulator API is available on the only board
using this driver so far, extend the driver with a bias control function
which will request virtual power to the codec chip from that virtual
regulator, and will supersede the present implementation existing at the
sound card level.
Thanks to the regulator sharing mechanism, both the old (the sound card)
and the new (the codec) implementations should coexist smoothly until
the sound card file is updated. For this to work as expected, update the
sound card .set_bias_level callback to not touch codec->dapm.bias_level.
While extending the cx20442 structure, drop unused control_type member.
Created against linxu-3.2-rc6, tested on top of patch 1/4 "ARM: OMAP1:
ams-delta: set up a regulator over the modem reset GPIO pin".

This functionality has already been implemented in the cx20442 codec
driver (commit f75a8ff67d161b5166a2c2360bb2ffaefd5eb853, "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.

After the CX20442 codec driver already takes care of enabling the codec
power for itself (commit f75a8ff67d161b5166a2c2360bb2ffaefd5eb853,
"ASoC: cx20442: add bias control over a platform provided regulator"),
but before dropping the old bias control method from the Amstrad Delta
ASoC sound card file, which in fact keeps the modem power always on,
even on the ASoC device close for now, extend the modem setup with a
power management callback which toggles the regulator up to the modem's
needs, reusing the previously set up regulator consumer for this. Also,
drop the MODEM_NRESET pin setup from the modem initialization procedure,
as this operation was already ineffective since patch 1/3, and not
needed because the regulator is set up as initially enabled.
Depends on patch 1/3 "ARM: OMAP1: ams-delta: set up regulator over modem
reset GPIO pin" to apply cleanly.
