Dynamic hardware clock gating is supported for most multimedia
ahb clocks on 8960v2 and axi clocks are supported on 8960v3.
Detect the SoC version and put the ahb and axi clocks into
hardware control appropriately.

Add support for hardware clock gating on branch clocks. Do this
in a few steps:
o At clock registration time, check to see if the branch is not
in hardware gated mode and fix up the branch data structure
as appropriate
o When a clk_reset() is asserted take the branch out of
hardware control so the reset can propagate if the clock
is enabled
o When a clk_reset() is deasserted put the branch back into
hardware control
Add three new ops to the clk_ops structure to support the above.
void (*enable_hwcg)(struct clk *clk);
void (*disable_hwcg)(struct clk *clk);
int (*in_hwcg_mode)(struct clk *clk);
{enable,disable}_hwcg() should enable and disable hardware clock
gating if possible. in_hwcg_mode() should return either a
non-zero value or a zero indicating whether the clock is
currently in hardware gating mode or not in hardware gating mode
respectively.
Use in_hwcg_mode() to detect when to skip the halt checks for a
branch and when to disable/enable hardware gating mode while
measuring clocks. This is particularly important for measurement
because we don't want to put a clock into hardware gating mode
accidentally after we measure the clock if the clock wasn't in
hardware gating mode to begin with.
Also expose a debugfs node indicating whether or not this clock
supports hardware gating. This should aid in debugging problems
due to hardware gating.

Instead of duplicating the simple soc_clk_reset() function for
each SoC's rcg clock, implement a generic rcg clock reset
function. 7x30 is different, but that's ok because we already
have a separate reset function for 7x30.

In back to back recording for an error case, the state is not
handled properly and the system hangs. So for graceful exit,
in error case ensure that the state is set properly.

Add freq and L2 tables for 8930 using the slow part voltage data.
Need to update regulators, voltage and bus bandwidth in later
patches.

Currently the code checks that the voltage readings for 0volts and
25mV are within a certain range. If it falls outside this range, the
code limits the value.
This limiting leads to error in calculating the battery current. Remove
the checks.

Create a platform driver to manage the Q6v3 instead of having a
module that exists for any 8660 target. This allows us to add
platform devices when the device really exists.

If the ringbuffer isn't idle, the GPU is probably in
SLUMBER or SUSPEND which are very idle states. This
function probably still shouldn't be called, so WARN
instead.
