TI has added new processors to the OMAP3 family. This patch enhances
the code in sysinfo.c to detect which family member is present.

This helps to clean up the include/ directory so that it only contains
non-architecture-specific headers and also matches Linux's directory
layout which many U-Boot developers are already familiar with.

v7_flush_dcache_all, because it depends on omap ROM code is not
generic. Rename the function to 'invalidate_dcache' and move it
to the omap cpu directory.
Collect the other omap cache routines l2_cache_enable and
l2_cache_disable with invalide_dcache into cache.S. This
means removing the old cache.c file that contained l2_cache_enable
and l2_cache_disable.
The conversion from cache.c to cache.S was done most through
disassembling the uboot binary. The only significant change was
to change the comparision for the return of get_cpu_rev from
cmp r0, #0
beq earlier_than_label
Which was lost information to
cmp r0, #CPU_3XX_ES20
blt earlier_than_label
The paths through the enable routine were verified by
adding an infinite loop and seeing the hang. Then
removing the infinite loop and seeing it continue.
The disable routine is similar enough that it was not
tested with this method.
Run tested by cold booting from nand on beagle and zoom1.
Compile tested on MAKEALL arm.

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.

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 */
}
