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.

kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.
This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel. A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).
Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.
