Client driver has a new feature requirement to acquire the number
of unused descriptors in the descriptor FIFO of a pipe; Add this
support in SPS driver.

Program the Auxiliary Control Regiater(ACTLR.SMP) to switch
from Symmetric MultiProcessing Mode(SMP) to Asymmetric Multi
Processing Mode(AMP) while entering into the GDFS power mode.
This enables the CPU to be taken out of coherency by preventing
the CPU from receiving cache and TLB maintenance operations
broadcast by other CPUs in the system.

RUMI address offsets are in 0x20200000 range, update the
PHYS_OFFSET and zreladdr to match this. This would also
change the offsets for the simulation to match that of
RUMI platform so as to allow the same image to be used on
both platforms.

Currently "msm_pm_write_boot_vector" is under CONFIG_MSM_SCM
configuration. Which is true for targets having TZ. But this
functionality is required for 8625 traget as well hence moving
this function outside of the configuration.

Since a CPU will read the msm_pm_pc_pgd value as it comes
up from power collapse when caches are disabled, it needs
to be guaranteed that the value has been written to memory
before any CPU power collapses.

The boot vector will need to be cleaned in the outer cache
after being written to ensure that it can be read by a CPU
which is waking up from power collapse. Calling
v7_flush_dcache_all is not sufficient on targets which
have an outer cache.
There is currently no requirement for the boot vector write to
happen in an assembly environment, and moving it to C makes
cleaning the outer cache easier.

The power collapse path is simplified if a noncached area is
used for the purpose of saving register state prior to power
collapsing. This is especially beneficial in the case of targets
with an outer cache, where the process of cleaning the register
state would require complex operations.

ION is a memory manager used by kernel and user
space clients to efficiently share buffers.
Add support for ION to 9615 target, as it is needed
for audio and power collapse. This commit will reserve
a total of 1mb of system memory (as reservations are
rounded up to megabyte boundaries).
A corresponding change to power management boot code
is also needed with this. When ION is enabled, the
method previously used by the PM code to allocate and
map the boot area for 9x15 does not work anymore. That
area must be allocated with a different API.

The driver has hardcoded dependency for period size on sample rate.
This restricts driver from being used for all sample rate and period
size combinations.
The driver also introduces an unnecessary delay in giving the first
buffer to dsp both for playback and record case. resulting in delay
in start of session.
