arm: omap4: panda: Add reading of the board revision
Detect if we are running on a panda revision A1-A6,
or an ES panda board. This can be done by reading
the level of GPIOs and checking the processor revisions.
This should result in:
Panda 4430:
GPIO171, GPIO101, GPIO182: 0 1 1 => A1-A5
GPIO171, GPIO101, GPIO182: 1 0 1 => A6
Panda ES:
GPIO2, GPIO3, GPIO171, GPIO48, GPIO182: 0 0 0 1 1 => B1/B2
GPIO2, GPIO3, GPIO171, GPIO48, GPIO182: 0 0 1 1 1 => B3
Set the board name appropriately for the board revision that
is detected.
Update the findfdt macro to load the a4 device tree binary.
