The series applies after [1].

The series supports L1TCM which is a high performance memory region in
MT8192 SCP.

The 1st patch replaces platform_get_resource_byname() and
devm_ioremap_resource() pairs per [2] suggested.

The 2nd patch enables MPU for all memory regions.  The patch was
independent but merged to this series per [3] suggested.

The 3rd patch adds a new reg-name "l1tcm" for L1TCM.

The 4th patch supports L1TCM in the firmware loader.  Note that MT8192
SCP is still under development.  The patch breaks early MT8192 SCP
firmware which should only break our own development environment.

Changes from v2[4]:
- Rebases the series to [1].

Changes from v1[5]:
- Adds 2 patches at beginning of the series.
