scsi: ufs: qcom: Drop custom Android boot parameters
The QCOM UFS driver requires an androidboot.bootdevice command line
argument matching the UFS device name. If the name is different, it
refuses to probe. This androidboot.bootdevice is provided by stock/vendor
(from an Android-based device) bootloader.
This does not make sense from Linux point of view. Driver should be able
to boot regardless of bootloader. Driver should not depend on some Android
custom environment data.
