[PATCH 1/2] HID: multitouch: rename MT_CLS_EGALAX_P80H84 to MT_CLS_EGALAX_WIN8

[buingoc67]

From: hmtheboy154 <buingoc67@gmail.com>

The Dell Pro Rugged 12 Tablet RA02260 uses an i2c touchscreen from
eGalax that exposes the same HID_GROUP_MULTITOUCH_WIN_8 as the
P80H84 and also requires the same quirks to make multitouch work.

Rename the class to MT_CLS_EGALAX_WIN8 for more general use.
