OMAP3: remove unused code from the ASM sleep code

From: Richard Woodruff
Analysis in TI kernel with ETM showed that using cache mapped flush
in kernel instead of SO mapped flush cost drops by 65% (3.39mS down
to 1.17mS) for clean_l2 which is used during sleep sequences.

From: Eduardo Valentin
Limitation i583: Self_Refresh Exit issue after OFF mode
Issue:
When device is waking up from OFF mode, then SDRC state machine sends
inappropriate sequence violating JEDEC standards.
Impact:
OMAP3630 < ES1.2 is impacted as follows depending on the platform:
CS0: for 38.4M
If the TPA6130 is compiled as module the id and power_gpio values are
arbitrary at module probing time since the rx51_tpa6130a2_data was marked as
__initdata. Fix this by using __initdata_or_module. Then __initdata is
defined only if the kernel is built without CONFIG_MODULES and omitted
otherwise.

Thanks for your comments on this patch. I'll plan to use the revised
version, without the function pointers.
