[PATCH] Fix ili210x touchdata coordinates endianness.

[Michael John Sakellaropoulos <mjsakellaropoulos@gmail.com>]

This fixes how coordinates are parsed from ili210x touchdata. Through observation 
and manual probing of the i2c bus, we have confirmed that the values stored in 
the registers are Little Endian.
(Tested on Amazon Kindle Fire Gen1 : arch/arm/boot/dts/omap4-kc1.dts)

This patch is a follow-up to the earlier one by Hansem Ro. I am also working on another patch
that queries the touchscreen controller for the active panel resolution (via REG_PANEL_INFO)
so we can report the correct resolution to evdev (right now it's hardcoded).
