igep00x0: enable the use of a plain text file

Based on commit cf073e49bc3502be1b48a0e3faf0cde9edbb89db for beagleboard

Using the new env import command it is possible to use plain text files instead
of script-images. Plain text files are much easier to handle.

E.g. If your boot.scr contains the following:
 -----------------------------------
setenv dvimode 1024x768-16@60
run loaduimage
run mmcboot
-----------------------------------
you could create a file named uEnv.txt and use that instead of boot.scr:
 -----------------------------------
dvimode=1024x768-16@60
uenvcmd=run loaduimage; run mmcboot
-----------------------------------
The variable uenvcmd (if existent) will be executed (using run) after uEnv.txt
was loaded. If uenvcmd doesn't exist the default boot sequence will be started,
therefore you could just use
-----------------------------------
dvimode=1024x768-16@60
-----------------------------------
as uEnv.txt because loaduimage and mmcboot is part of the default boot sequence

codes.

Support for the Ctrl modifier is provided. The left and right ctrl keys are
dealt with in the same way.

This uses the new keyboard input library (drivers/input/input.c) to decode

is also used to decode (row, column) key positions into key codes.

The intent is to make this driver purely about dealing with the hardware.

Key detection before the driver is loaded is supported. This key will be
picked up when the keyboard driver is initialized.
