[PATCH 1/3] Input: bu21013_ts - Request a regulator that actually exists

Currently the BU21013 Touch Screen driver requests a regulator by the
name of 'V-TOUCH', which doesn't exist anywhere in the kernel. The
correct name, as referenced in platform regulator code is 'avdd'. Here,
when we request a regulator, we use the correct name instead.

The regulator should be requested using whatever the name for the supply
in the datasheet - AVDD does sound very pluasible but it'd be good to
check.

Right. 'avdd' is correct.
