msm: scm: Add scm_call_noalloc and helper macros

Currently, scm_call internally calls kmalloc() to allocate a command
buffer structure. This prevents scm_call from working before kmalloc
structures are initialized or during atomic contexts. Allow clients
to pass in a pre-allocated buffer for scm_call to be used for internal
structures.

arm: Add ARCH_RANDOM Kconfig

Some boards may support architecture generated random numbers. Add
the appropriate Kconfig.

msm: implement ARCH_RANDOM

Currently, the software random number generator is not intialized
until relatively late in the boot process. Software that relies on
random numbers early will not be reliable. Entropy sources are
available early but not early enough for some use cases which means
that moving the software random number generation earlier is not an
option. As an alternate solution, implement the functions associated
with CONFIG_ARCH_RANDOM. These functions currently make a call into
trustzone to get reliable random numbers. The functions are disabled
once the regular random number generator is sufficiently reliable.

init: Move stack canary initialization after setup_arch

Stack canary intialization involves getting a random number.
Getting this random number may involve accessing caches or other
architectural specific features which are not available until
after the architecture is setup. Move the stack canary initialization
later to accomodate this.

msm: kgsl: Fix memory leak of DRM GEM object structure.

This changes frees the DRM GEM object structure in
kgsl_gem_free_object function. kgsl_gem_free_object is
called from DRM module after the last refrence to the
object has been lost.
