omap_enable_smartreflex_on_init is meant to be used by boards
which would like to have SR enabled by default on the platform, while
omap_devinit_smartreflex is used by pm code, the protos are defined
in pm.h. This header should be included to ensure that sr_device
function definitions match the prototypes.
including pm.h fixes the sparse warnings (with CONFIG_OMAP_SMARTREFLEX=y):
arch/arm/mach-omap2/sr_device.c:138:13: warning: symbol 'omap_enable_smartreflex_on_init' was not declared. Should it be static?
arch/arm/mach-omap2/sr_device.c:143:12: warning: symbol 'omap_devinit_smartreflex' was not declared. Should it be static?

This patch extends the smartreflex framework to support
OMAP4. The changes are minor like compiling smartreflex Kconfig
option for OMAP4 also, and a couple of OMAP4 checks in
the smartreflex framework.
The change in sr_device.c where new logic has to be introduced
for reading the efuse registers is due to the fact that in OMAP4
the efuse registers are 24 bit aligned. A __raw_readl will
fail for non-32 bit aligned address and hence the 8-bit read
and shift.

This patch adds support for device registration of various
smartreflex module present in the system. This patch introduces
the platform data for smartreflex devices which include
the efused n-target vaules, a parameter to indicate
whether smartreflex autocompensation needs to be
enabled on init or not. An API
omap_enable_smartreflex_on_init is provided for the
board files to enable smartreflex autocompensation during
system boot up.
