[PATCH 1/5] ARM: OMAP2+: Fix access to reserved smartreflex registers for dra7

[Tony Lindgren]

The TRM has marked dra7 SmartReflex as reserved and we should not
touch those registers as pointed out by Nishanth Menon <nm at ti.com>.
So let's remove these registers.

If it later on turns out that these registers are needed for
some reason, the struct omap_hwmod_addr_space needs be mapped in
the device tree instead.
