The OMAP2 clock code was missing code to associate clocks with clockdomains
at registration time; fix this.

Resolves "Unhandled fault: alignment exception (0x001) at 0xc02c1b4e" (address
may vary) panic during clock framework init on OMAP2.  The alignment error
was caused by an attempt to dereference a pointer to a string (1-byte aligned)
as if it were a pointer to a structure.

Add the omap3_core_dpll_m2_set_rate() function to the OMAP3 clock code,
which calls into the SRAM function omap3_sram_configure_core_dpll() to
change the CORE DPLL M2 divider.  (SRAM code is necessary since rate changes
on clocks upstream from the SDRC can glitch SDRAM accesses.)

Use this function for the set_rate function pointer in the dpll3_m2_ck
struct clk.  With this function in place, PM/OPP code should be able to
alter SDRAM speed via code similar to:

      clk_set_rate(&dpll3_m2_ck, target_rate).

3430ES2+ CORE DPLL M2 divider can divide by 1 to 31, unlike ES1, which
was more limited.  The SRAM code currently only supports dividing by 1
or 2, but we should mask off the full range of bits to guard against
the event that the previous contents of CM_CLKSEL_PLL1 included an M2
divider > 2.

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.
