Subject: [PATCH v1 1/3] Outsourced sensor masks to PCI driver header.

From: Richard Neumann <mail@...hard-neumann.de>

Outsourced the mask definitions of the four sensors into
the PCI device driver header file for later use with the quirks.
Also renamed the values from *_EN to *_MASK to emphasize that
they are actually sensor bitmasks for matching against activestatus.

Signed-off-by: Richard Neumann <mail@...hard-neumann.de>
