This reverts commit 84ee19bffc9306128cd0f1c650e89767079efeff.
The commit above made quirks with an OEMID fail to be applied, as they were checking card->cid.oemid for the full 16 bits defined in MMC_FIXUP macros but the field would only contain the bottom 8 bits.
eMMC v5.1A might have bogus values in OEMID's higher bits so another fix will be made, but it has been decided to revert this until that is ready.

Applied for fixes, thanks!
Kind regards Uffe
Here's the revert as discussed in "mmc: truncate quirks' oemid to 8 bits"' patch thread. Feel free to ignore if you already have something, I just checked your -next branch quickly and might have missed it.
