msm: pm-8x60: Use generic clk apis during power collapse

The power management code calls in acpuclk code directly to switch to a
always on clock source during power collapse there by turning off the
HFPLL during any power collapse. The Krait clock management is switching
to use clocks ops model. To necessitate the change, the power management
code will register for CPU/L2 clock sources and disables the
corresponding clocks during power collapse.

Add a DT node to indicate if the clock sources are synchronized across
the cores/L2, to prevent querying on clock sources that might not be
available on certain targets. Also, clk_get() doesn't currently support
deferred probe, change the compile order to include pm-8x60 after clocks
driver to ensure that clock drivers get probed before pm-8x60.

msm: idle: Use ARM suspend/resume APIs to restore during warmboot

ARM generic cpu_suspend/resume APIs restore the necessary CP15 registers
to a known state when resuming from a reset state. Use of generic
suspend/resume APIs allows the msm warmboot code to not care about
restoring core registers used by ARM kernel. Also, the PM subsystem no
longer needs to allocate page table or uncached memory to save CPU
registers.

While at it convert most of the assembler code into respective C
function except for warmboot code that executes with MMU turned off.
Also, the idle subsystem no longer needs to manage a  page table or
uncached memory to save CPU registers.

msm: pm: Rename pm-8x60.c to msm-pm.c

pm-8x60.c doesn't accurately reflect the current list of targets that
are supported. So renaming them to msm-pm.c to be more inline with the
msm chipsets.
