* changes:
msm: pm2: Use PER CPU variable to log the idle stats
msm: pm2: Change the initialization sequence of "msm_pm_init_done"
msm: pm2: Use a different kernel API to get the sleep length
Replace local static varaible with per cpu static varaible
to log the individual cores idle statistics information
correctly.

Set the "msm_pm_init_done" variable after populating the idle
statistics data for both the cores. Setting this varaible before
initializing the idle stats causes the kernel exception (division
by zero). This is happening because one core is doing the driver
init and another core finds idle time and execute the arch_idle
to do a low power mode and also is trying to log the idle stats
information where another core is not prepared yet.

Currently pm2 driver calls the "msm_timer_enter_idle" &
msm_timer_exit_idle" API's for all the power modes (i.e.
SWFI, GDFS/StandalonePC) to get next timer expiration &
time sync with modem respectively. Use these API's only
when the system decide to enter into a modem assisted PC
otherwise use a differnt API to get the sleep length.

Currently PM driver uses the memory given by the "memblock_alloc"
api. These initial memory bytes are programmed with warm boot entry
sequences to come out of the low power modes. Currently this API is
causing the system instability with 1GB DDR parts and HIGH MEM is
enabled. To resolve this issue use a different API to allocate the
memory i.e memblock_remove.

The default writeback size (6MB) is as per primary interface. For
mixer1 writeback to be enabled, writeback size should be more than
the maximum resolution supported by mixer1 which is 1080P.
Increase writeback memory size for mixer1 writeback to 12MB.

This reverts commit 7dd2266ae3.
It was a mistake to move the usb driver to the clock apis for XO
buffer voting. Due to an RPM design CXO and D0 are the same but
we would like to hide that from the users of the buffers.
Therefore the msm_xo driver itself remaps the D0 buffer request
to the cxo clock until the RPM is fixed.

Upon wakeup source detection, modem bring's the core0 out of
reset. The recomendation for core0 in 8x25 is to put the core1
into GDFS till hotplug sw brings it online.
Since core1 is not yet enabled, program the top CSR from core0
context and drive the SPM1 to put the core1 in to GDFS. Once
core1 is put into GDFS disable the top csr and enable the SPM1
control for core1.
Enable the scu as well while coming out of power collapse which
facilitates the coherency between shared data across the cores.

Currently, show_regs calls __backtrace which does
nothing if CONFIG_FRAME_POINTER is not set. Switch to
dump_stack which handles both CONFIG_FRAME_POINTER and
CONFIG_ARM_UNWIND correctly.
__backtrace is now superseded by dump_stack in general
and show_regs was the last caller so remove __backtrace
as well.
