The Beagle rev Cx and Overo boards are using both SDRC CSes. The MUX
setting is needed for the second CS clock signal to allow the 2 RAM
parts to be put in self-refresh correctly. This also works on rev B
Beagle boards with 128M of RAM.

The board-types defined in struct omap3_sysinfo seem to be
unused. The function display_board_info() is passed
board type as an argument; which is ignored.
This patch removes all uses of board-type, related definitions
and functions.

With BeagleBoard revision C some HW changes are introduced (e.g. PinMUX)
which might need different software handling. For this, GPIO pin 171 (GPIO
module 6, offset 11) can be used to check for board revision. If this pin
is low, we have a rev C board. Else it must be a revision Ax or Bx board.
To handle board differences you can call function beagle_get_revision().
E.g.:
if (beagle_get_revision()) {
/* do special revision C stuff here */
}
