mmc: sdhci-msm: drop redundant of_device_id entries

This reverts three commits:
1. Revert "mmc: sdhci-msm: Add compatible string check for sdx65"
   This reverts commit 9537068.

2. Revert "mmc: sdhci-msm: Add compatible string check for sm8150"
   This reverts commit 5acd6ad.

3. Revert "mmc: sdhci-msm: Add SoC specific compatibles"
   This reverts commit 466614a.

The oldest commit 466614a ("mmc: sdhci-msm: Add SoC specific
compatibles") did not specify what benefits such multiple compatibles
bring, therefore assume there is none.  On the other hand such approach
brings a lot of churn to driver maintenance by expecting commit for
every new compatible, even though it is already covered by the fallback.

There is really no sense in duplicating of_device_id for each
variant, which is already covered by generic compatible fallback
qcom,sdhci-msm-v4 or qcom,sdhci-msm-v5.
