ARM: OMAP: move plat-omap/include/plat/sdrc.h into mach-omap2/sdrc.h

Remove arch/arm/plat-omap/include/plat/sdrc.h by folding its contents
into arch/arm/mach-omap2/sdrc.h.  The objective is to assist Tony in
cleaning out arch/arm/plat-omap/, as his upstreams request.

- * These values represent the number of memory clock cycles between
- * autorefresh initiation.  They assume 1 refresh per 64 ms (JEDEC), 8192
- * rows per device, and include a subtraction of a 50 cycle window in the
- * event that the autorefresh command is delayed due to other SDRC activity.
- * The '| 1' sets the ARE field to send one autorefresh when the autorefresh
- * counter reaches 0.
- *
- * These represent optimal values for common parts, it won't work for all.
- * As long as you scale down, most parameters are still work, they just
- * become sub-optimal. The RFR value goes in the opposite direction. If you
- * don't adjust it down as your clock period increases the refresh interval
- * will not be met. Setting all parameters for complete worst case may work,
- * but may cut memory performance by 2x. Due to errata the DLLs need to be
- * unlocked and their value needs run time calibration. A dynamic call is
- * need for that as no single right value exists acorss production samples.
- *
- * Only the FULL speed values are given. Current code is such that rate
- * changes must be made at DPLLoutx2. The actual value adjustment for low
- * frequency operation will be handled by omap_set_performance()
- *
- * By having the boot loader boot up in the fastest L4 speed available likely
- * will result in something which you can switch between.
