Subject: [PATCH v2 0/6] Describe the IMEM present in Qualcomm IPQ SoC's

Qualcomm IPQ SoCs also have the IMEM region and used for the various
debugging purposes like storing system restart reason and so on. As a
preparatory work, first describe the IMEM region and susbsequently add
the required features.

Across all SoCs, only initial 4KB can be accessed by all the masters in the
SoC, remaining regions are access protected.
