Some OMAP3 boards (Beagle Cx, Overo, RX51, Pandora) have 2
SDRAM parts connected to the SDRC.
This patch adds the following:
- add a new argument of type omap_sdrc_params struct*
to omap2_init_common_hw and omap2_sdrc_init for the 2nd CS params
- adapted the OMAP boards files to the new prototype of
omap2_init_common_hw
- add the SDRC 2nd CS registers offsets defines
- adapt the sram sleep code to configure the SDRC for the 2nd CS
Note: If the 2nd param to omap2_init_common_hw is NULL, then the
parameters are not programmed into the SDRC CS1 registers
Tested on 3430 SDP and Beagleboard rev C2 and B5, with
suspend/resume and frequency changes (cpufreq).

For a given SDRAM clock rate, SDRAM chips require memory controllers
to use a specific set of timing minimums and maximums to transfer data
reliably. These parameters can be different for different memory chips
and can also potentially vary by board.
This patch adds the infrastructure for board-*.c files to pass this
timing data to the SDRAM controller init function. The timing data is
specified in an 'omap_sdrc_params' structure, in terms of SDRC
controller register values. An array of these structs, one per SDRC
target clock rate, is passed by the board-*.c file to
omap2_init_common_hw().
This patch does not define the values for different memory chips, nor
does it use the values for anything; those will come in subsequent patches.

Most of the omap1 MMC boards got broken by an earlier patch
138ab9f8321f67c71984ca43222efa71b0a0a0a9. If you look closely,
the MMC init funtions are pretty much just stubs.
Remove broken init code to make room for cleaner MMC init code.

This just leaves include/asm-arm/plat-* to deal with.

Remove includes of asm/hardware.h in addition to asm/arch/hardware.h.
Then, since asm/hardware.h only exists to include asm/arch/hardware.h,
update everything to directly include asm/arch/hardware.h and remove
asm/hardware.h.

Add the omap2_set_globals_{242x,243x,343x}() functions. These
functions are called early upon boot in the map_io() functions in the
board-specific init files.
This patch was accidentally left out of the earlier series.
This fixes omap2 booting as noted by Kyungmin Park <kmpark@infradead.org>.

Patch from Nicolas Pitre
This field is redundent since it must be equal to PHYS_OFFSET anyway.
Now that no code uses it anymore, mark it deprecated and remove all
initializations from the tree.

Patch from Tony Lindgren
This patch adds support for omap24xx series of processors.
The files live in arch/arm/mach-omap2, and share common
files with omap15xx and omap16xx processors in
arch/arm/plat-omap.
Omap24xx support was originally added for 2.6.9 by TI.
This code was then improved and integrated to share common
code with omap15xx and omap16xx processors by various
omap developers, such as Paul Mundt, Juha Yrjola, Imre Deak,
Tony Lindgren, Richard Woodruff, Nishant Menon, Komal Shah
et al.
