Bartosz Golaszewski 178e19c0df firmware: qcom: scm: add support for SHM bridge operations ...

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 low-level primitives for enabling SHM bridge support as well as
creating and destroying SHM bridges to qcom-scm.
