This series adds initial support for the Samsung Galaxy Tab 2
(samsung-espresso7/10) series of devices. It adds support for 6 variants
(P3100, P3110, P3113, P5100, P5110, P5113). Downstream categorised them
based on 3G and WiFi, but since they use different panel, touch
controllers, batteries, I decided to categorise them based on screen
size as espresso7 and espresso10.

It adds basic functionality for both the models including panel, drm,
sdcard, touchscreen, mmc, wifi, bluetooth, keys, battery, fuel gauge,
pmic, sensors.
