ufs: Add UFSHCD_QUIRK_BROKEN_64BIT_ADDRESS

Browse source 
Add UFSHCD_QUIRK_BROKEN_64BIT_ADDRESS for host controllers which do not
support 64-bit addressing.

Ported from Linux kernel commit
6554400d6f66 ("scsi: ufs: core: Add UFSHCD_QUIRK_BROKEN_64BIT_ADDRESS")
with ufs_scsi_buffer_aligned() based on U-Boot generic bounce buffer.
