firmware: qcom: scm: Introduce CP_SMMU_APERTURE_ID

The QCOM_SCM_SVC_MP service provides QCOM_SCM_MP_CP_SMMU_APERTURE_ID,
which is used to trigger the mapping of register banks into the SMMU
context for per-processes page tables to function (in case this isn't
statically setup by firmware).

This is necessary on e.g. QCS6490 Rb3Gen2, in order to avoid "CP | AHB
bus error"-errors from the GPU.

Introduce a function to allow the msm driver to invoke this call.
