Move the existing clock code in mach-msm to the common clock
framework. We lose our capability to set the rate of and enable a
clock through debugfs. This is ok though because the debugfs
features are mainly used for testing and development of new clock
code.
To maintain compatibility with the original MSM clock code we
make a wrapper for clk_reset() that calls the struct msm_clk
specific reset function. This is necessary for the usb and sdcc
devices on MSM until a better suited API is made available.

There are no users of this API anymore so let's just remove it.
If a need arises in the future we can extend the common clock API
to handle it.

Not all devices use proc_comm and determining if a clock is local
vs. remote is fragile when done by comparing clk_ops pointers.
Instead, implement an is_local() function for all clk_ops to
determine if the clock is local. Doing this allows us to remove
the last references to clk_ops_pcom from clock.c and compile it
for targets with CONFIG_MSM_PROC_COMM=n.
We don't need to set the clk_ops at runtime until 7x30 local
clock detection comes in. Right now it's just complicating things
so just set the ops pointer statically.

There are currently 3 separate directories for clock debugging in
debugfs: clk_enable, clk_rate, and clk_local. Each of these
directories contains a list of clocks. This is rather annoying
when you are focusing on one clock and want to enable/disable it
and then check its rate. You either have to cd to the other
directory or cat ../clk_rate/<clk>.
Invert the layout so that there is one clock directory containing
a directory for each clock. Inside each respective clock
directory place an enable, rate, and is_local file relating to
the clk_enable, clk_disable, and clk_local directories that exist
today.

The clock debugfs code is large enough, and easy enough to separate,
that it deserves its own file which is compiled only when
CONFIG_DEBUG_FS is enabled.
Also, cleanup header file #includes that are no longer required.
