We need to divide the 15xx/16xx offset by 2 for 7xx. Use bank->stride for that. This allows us to get rid of the duplicate defines for the MPUIO registers. Note that this will cause omap-keypad.c driver to not work on 7xx. However, the right fix there is to move over to matrix_keypad instead as suggested by Cory Maccarrone <darkstar6262@gmail.com> and Janusz Krzysztofik <jkrzyszt@tis.icnet.pl>.
