The touchscreen works in two modes, wait trigger mode and auto-semi
mode. The device starts in wait trigger mode and waits until pressure
is detected, then device sets WT_INT bit and raises an interrupt.
The driver should put the device into auto-semi mode and prepare for
reading first X and then Y coordinates. When coordinate data is ready
the driver sets ADC_INT bit and raises interrupt again.

This patch adds an accelerated driver for Atmel AVR32 AT32AP700X
microprocessors. It uses interrupts on the channel B in the AC97
controller. Thus, offloading the work queue in the wm97xx-ts driver.

The driver has been tested with Atmel AVR32 AT32AP7000 and Wolfson
WM9712 codec.

The driver can also be easily modified to support Atmel AT91 devices, as
AT91 and AVR32 share the same AC97C module.

Currently the support for each WM97xx touchscreen model is compiled out
by default, meaning that the default configuration when the driver is
built is for it to support no hardware.  This is suboptimal and leads to
problems like distribution kernels shipping a non-functional driver.

Change the default to support all controllers and update the help text
to reflect this.
