firmware: qcom: tzmem: enable SHM Bridge support
SHM Bridge is a safety mechanism allowing to limit the amount of memory
shared between the kernel and the TrustZone to regions explicitly marked
as such.
Add a variant of the tzmem allocator that configures the memory pools as
SHM bridges. It also enables the SHM bridge globally so non-SHM bridge
memory will no longer work with SCM calls.
If enabled at build-time, it will still be checked for availability at
run-time. If the architecture doesn't support SHM Bridge, the allocator
will fall back to the generic mode.
