[PATCH 1/4] dt-bindings: memory: mediatek: Add mt8188 SMI reset control binding

[friday.yang]

To support SMI clamp and reset operation in genpd callback, add
SMI LARB reset register offset and mask related information in
the bindings. Add index in mt8188-resets.h to query the register
offset and mask in the SMI reset control driver.

+description: |
+  This reset controller node is used to perform reset management
+  of SMI larbs on MediaTek platform. It is used to implement various
+  reset functions required when SMI larbs apply clamp operation.
+
+  For list of all valid reset indices see
+    <dt-bindings/reset/mt8188-resets.h> for MT8188.
