The function display_board_info() displays incorrect
silicon revision - based on the return value from
function get_cpu_rev().
This patch fixes the problem.

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.

Use the functions print_cpuinfo() and checkboard() to
display the cpu and board specific information.
These functions reuse content from the existing function
display_board_info() - which has been removed.
Also, updated the existig OMAP3 configurations to
define:
- CONFIG_DISPLAY_CPUINFO
- CONFIG_DISPLAY_BOARDINFO

This patch adds OMAP3 cpu type auto detection based on OMAP3 register
and removes hardcoded values.

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 */
}
