dt-bindings: mmc: sdhci-msm: constrain reg-names per variants
The entries in arrays must have fixed order, so the bindings and Linux driver expecting various combinations of 'reg' addresses was never actually conforming to guidelines. The 'core' reg entry is valid only for SDCC v4 and lower, so disallow it in SDCC v5. SDCC v4 supports CQE and ICE, so allow them, even though the qcom,sdhci-msm-v4 compatible is used also for earlier SoCs with SDCC v2 or v3, so it is not entirely accurate.
