ARM: msm: fix compilation flags for MSM_SCM
CONFIG_MSM_SCM uses the smc instruction, which with some
toolchains requires a ".arch_extension" directive.

msm: scm: Check for interruption immediately
When we're interrupted on the secure side, we should just issue
another smc instruction again instead of replaying the arguments
to smc. Fix it.

msm: scm: Fix improper register assignment
Assign the registers used in the inline assembly immediately
before the inline assembly block. This ensures the compiler
doesn't optimize away dead register assignments when it
shouldn't.

msm: scm: Mark inline asm as volatile
We don't want the compiler to remove these asm statements or
reorder them in any way. Mark them as volatile to be sure.

msm: Secure Channel Manager (SCM) support
SCM is the protocol used to communicate between the secure and
non-secure code executing on the applications processor. The
non-secure side uses a physically contiguous buffer to pass
information to the secure side; where the buffer conforms to a
format that is agreed upon by both sides. The use of a buffer
allows multiple pending requests to be in flight on the secure
side. It also benefits use cases where the command or response
buffer contains large chunks of data.
