[PATCH v3 1/2] dt-bindings: nvmem: sprd,sc2731-efuse: convert to YAML

Changes in V3:
  - add Conor's R-b
  - rebase on next-20240805
  - add lore links to V1 and V2 to the changelog

Changes in V2:
  - don't merge both SPRD eFuse bindings into one
    (ums312 now has separate bindings, see patch 2)
  - drop now unused clocks, clock-names

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

[Stanislav Jakubek]

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.
