Subject: [PATCH v3 2/2] dt-bindings: nvmem: sprd,ums312-efuse: convert to YAML

Convert the Spreadtrum UMS312 eFuse bindings to DT schema.
Adjust filename to match compatible.

Note: the UMS312 clock bindings include doesn't seem to exist (yet?), so
      the UMS512 one was used for the "CLK_EFUSE_EB" define.
