Stephen Boyd bd32344a6b msm: clock: Migrate to clkdev
Migrating to clkdev has several advantages:

 * Less code in mach-msm/clock.c

 * A more robust clk_get() implementation

 * clk_add_alias() support

 * clk_get_sys() support

In general, this will help board authors setup clock aliases and
break the dependency on device pointers in the clock tables.

Stephen Boyd 2a52220c89 msm: clock: Remove references to clk_ops_pcom
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.

Matt Wagantall d64560fe3e msm: clock: Move debugfs code from clock.c to clock-debug.c
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.

Stephen Boyd ce1c80fbaa msm: clock: Remove 7x30 and pcom includes from clock.h
clock.h includes clock-pcom.h and clock-7x30.h when it really
doesn't need to. Remove the includes and fixup breakages.

This code is dead or otherwise useless so just remove it.

Daniel Walker 3a790bbe79 msm: add handling for clocks tagged as CLK_MINMAX
CLK_MINMAX is used to denote clocks that have a wide variation
in possible frequencies. This handling just sets the min and
max values to the same value.

Daniel Walker 5e96da5d50 msm: generalize clock support.
The 'PCOM' method of clock control (commands issued to the radio
CPU) is shared across several (but not all) Qualcomm SOCs.
Generalize this clock mechanism so these other SOCs can be added.
