Currently spitz_ohci_init() that requests GPIO doesn't have
corresponding spitz_ohci_exit() which will gpio_free(). This causes
minor problems e.g. during resume when the OHCI device can't be resumed.

'mach-pxa' platforms currently rely on a bootloader to setup GPIO pins
and clear RDH (to enable inputs).

A kernel loaded by a 'minimal' bootloader, that doesn't touch any pins,
will not function correctly; inputs will remain disabled, even after the
pins are configured. The following change fixes the issue and has been
verified on Gumstix Verdex XL6P and a custom PXA270 platform.

GPIO17_SDATA_IN_1 and GPIO36_SDATA_IN_1 are originally designed for the 2nd
codec but unused on the board, yet they are initialized incorrectly by the
bootloader as the SDATA_IN_1 alternate function, thus causing AC97 fail to
work. Fix this issue by configuring these pins as normal GPIO to avoid the
noise from these pins being treated as signals from the 2nd codec.

Firstly, this patch makes the palm27x asoc driver a little more sane. Also,
since all affected devices use GPIO95 as AC97_nRESET, this patch sets that
properly. Affected are PalmT5, TX and LifeDrive.

MioA701 board's GPIO95 is the AC97 line. The other GPIO113
is not connected to the sound chip, but to the GSM chip as a
wakeup line.

It happens that when the pxa2xx_ac97 driver reconfigures the
gpio as an "out gpio" for AC97 reset (bug workaround), it
hangs the GSM chip.

As AC97 platform data now enables to specify the AC97 reset
line, use it.

Currently there are two possible platform datas for the PXA AC97 driver:
one supported by the generic AC97 driver only which provides callbacks
to allow board-specific configuration at stream startup and teardown,
and another for pxa2xx-ac97-lib which allows configuration of the reset
GPIO for PXA2xx CPUs.

Obviously this won't actually work when using the generic AC97 driver
since the drivers will attempt to parse the platform data in both
formats. Fix this by merging the two structures.

With this patch, the bq24022 battery charger is controlled by the USB
gadget framework (via gpio_vbus) when connected to USB.

To compile, this patch depends on the "regulator: Allow init data to be
supplied for bq24022" patch (queued for next in the regulator tree) to
add the init_data field to struct bq24022_mach_info.
It also depends on the "add optional OTG transceiver and voltage
regulator support to pda_power" patch (queued for next in the power
supply tree) to enable charging when connected to the AC charger.
