OMAP3 hwmod: drop most of the OCP_SYSCONFIG.CLOCKACTIVITY code
Earlier, the hwmod code had considered the OCP_SYSCONFIG.CLOCKACTIVITY
bits to be incremental power saving bits, controlling internal IP
block clock gates. This was a misapprehension. The CLOCKACTIVITY
bits are used to indicate, in advance, which clocks will be cut when
the module acknowledges an idle request. This enables the IP block to
take whatever action is necessary to complete any in-progress work
before asserting its IdleAck.
In the current Linux-OMAP code, this implies that the clock framework
should be changing module CLOCKACTIVITY bits as module clocks are enabled
and disabled. We don't do that yet, but in the future, we should.
This must wait until the clock tree is annotated with omap_hwmod pointers
(or vice-versa). In the meantime, drop most of the hwmod code that
controls CLOCKACTIVITY bits to avoid confusion.

OMAP3 hwmod: Add automatic OCP_SYSCONFIG AUTOIDLE handling
This patch fills in the OCP_SYSCONFIG.AUTOIDLE handling in the OMAP
hwmod code.
After this patch, the hwmod code will set the module AUTOIDLE bit
(generally <module>.OCP_SYSCONFIG.AUTOIDLE) to 1 by default upon
enable. If the hwmod flag HWMOD_NO_OCP_AUTOIDLE is set, AUTOIDLE will
be set to 0 upon enable. Upon module disable, AUTOIDLE will be set to
1.
Enabling module autoidle should save some power. The only reason to
not set the OCP_SYSCONFIG.AUTOIDLE bit is if there is a bug in the
module RTL, e.g., the MPUINTC block on OMAP3.

OMAP3: SDRC: Place SDRC AC timing and MR changes in CORE DVFS SRAM code behind Kconfig
The code that reprograms the SDRC memory controller during CORE DVFS,
mach-omap2/sram34xx.S:omap3_sram_configure_core_dpll(), does not
ensure that all L3 initiators are prevented from accessing the SDRAM
before modifying the SDRC AC timing and MR registers. This can cause
memory to be corrupted or cause the SDRC to enter an unpredictable
state. This patch places that code behind a Kconfig option,
CONFIG_OMAP3_SDRC_AC_TIMING for now, and adds a note explaining what
is going on. Ideally the code can be added back in once supporting
code is present to ensure that other initiators aren't touching the
SDRAM. At the very least, these registers should be reprogrammable
during kernel init to deal with buggy bootloaders. Users who know
that all other system initiators will not be touching the SDRAM can
also re-enable this Kconfig option.
This is a modification of a patch originally written by Rajendra Nayak
