The board supported by this driver has a 93x76 eeprom. Knowing this
information allows simplifying the code that reads the PCI bars to

On resume, the DMM resume handler will first reprogram the LUT to point
to the dummy page.  The subsequent resume handler in the omapdrm will call
into the DMM and reprogram each of the buffer objects.  This will ensure
that all of the necessary objects will be pinned into the DMM properly.

It also changes "Register" to "Registers" in
ANDROID_LOW_MEMORY_KILLER

Finally, all "help" instances are changed to "---help---",
as recommended by kconfig-language.txt in order to visually
aid developers.

staging: android: Fix two checkpatch issues in binder.c

This fixes two instances of
"static const char * array should probably be static const char * const"

I have seen other commits doing this in other files, so I am
assuming it should be done here as well.

Please tell me if this is wrong :)
