omap_hsmmc: Move gpio and regulator control from board file

This patch moves the setup code for GPIO's and Voltage
Regulators from the board file mmc-twl4030.c to the
driver omap_hsmmc.c.  PBIAS and other system control
configuration remains in the board file.

Moving GPIO code to the driver makes the board initialisation
code independent of when GPIO's are defined.  That makes the
board initialisation now entirely independent of its original
twl4030 roots.

Moving Voltage Regulator code to the driver allows for further
development of regulator support in the core MMC code.  It also
permits the MMC core to be compiled as a module, because the
board code no longer calls MMC core functions.

dynamically using switch setting information (S8: 1-4).

1. struct mtd_partition *parts
2. int nr_parts

A board file is expected to fill this structure and pass it to

omap: McBSP: Use cache when modifying individual register bits

Change the way McBSP registers are updated: use cached values instead of
relying upon those read back from the device.

With this patch, I have finally managed to get rid of all random
playback/recording hangups on my OMAP1510 based Amstrad Delta hardware. Before
that, values read back from McBSP registers to be used for updating them
happened to be errornous.

From the hardware side, the issue appeared to be caused by a relatively high
power requirements of an external USB adapter connected to the board's printer
dedicated USB port.

I think there is one important point that makes this patch worth of applying,
apart from my hardware quality. With the current code, if it ever happens to
any machine, no matter if OMAP1510 or newer, to read incorrect value from a
McBSP register, this wrong value will get written back without any checking.
That can lead to hardware damage if, for example, an input pin is turned into
output as a result.

Applies on top of patch 3 from this series:

Linus Torvalds [Sun, 7 Feb 2010 18:11:23 +0000 (10:11 -0800)]
Fix race in tty_fasync() properly

This reverts commit 703625118069 ("tty: fix race in tty_fasync") and
commit b04da8bfdfbb ("fnctl: f_modown should call write_lock_irqsave/
restore") that tried to fix up some of the fallout but was incomplete.

It turns out that we really cannot hold 'tty->ctrl_lock' over calling
__f_setown, because not only did that cause problems with interrupt
disables (which the second commit fixed), it also causes a potential
ABBA deadlock due to lock ordering.

Thanks to Tetsuo Handa for following up on the issue, and running
lockdep to show the problem.  It goes roughly like this:

 - f_getown gets filp->f_owner.lock for reading without interrupts
   disabled, so an interrupt that happens while that lock is held can
   cause a lockdep chain from f_owner.lock -> sighand->siglock.

 - at the same time, the tty->ctrl_lock -> f_owner.lock chain that
   commit 703625118069 introduced, together with the pre-existing
   sighand->siglock -> tty->ctrl_lock chain means that we have a lock
   dependency the other way too.

So instead of extending tty->ctrl_lock over the whole __f_setown() call,
we now just take a reference to the 'pid' structure while holding the
lock, and then release it after having done the __f_setown.  That still
guarantees that 'struct pid' won't go away from under us, which is all
we really ever needed.
