mmc: sdhci-msm: disable BKOPS feature

The BKOPS feature is supported for eMMC cards of version 4.41 and higher.
The BKOPS feature is one time programmable and once it was enabled on
a certain MMC card is cannot be disabled.

LA builds are often being used to verify phones that are targeted for
other HLOSes. Since not all the HLOSes implement the BKOPS features,
enabling this feature by default can cause instability when the phone
will be used by HLOSes other than LA.
