This introduces one functional change, the input device is now

Previously, tsc2007 would report as ABS_PRESSURE:
0              for no pressure (resistance infinite)
high value     for soft pressure (high resistance)
low value      for firm pressure (lower resistance)

This does not matter for most applications (e.g. GUI, Menu, Scrolling etc.)
where the ABS_PRESSURE is ignored and only BTN_TOUCH is processed to detect
screen taps.

Only some special graphics applications read the pressure channel and they
will be mixed up by this non-monotonic relation.

So we fix it to become:
0              for no pressure (resistance infinite)
low value      for soft pressure (high resistance)
high value     for firm pressure (lower resistance)

While this patch changes the values reported to userspace, ABS_PRESSURE is

Input: pwm-beeper - add optional amplifier regulator

This adds an optional regulator to the pwm-beeper device. This regulator
acts as an amplifier. The amplifier is only enabled while beeping in order
to reduce power consumption.

Tested on LEGO MINDSTORMS EV3, which has a speaker connected to PWM through
