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.
