Bart Van Assche 473cc51699 scsi: ufs: exynos: Fix DMA alignment for PAGE_SIZE != 4096 ...

[ Upstream commit 86bd0c4a2a ]

The Exynos UFS controller only supports scatter/gather list elements that
are aligned on a 4 KiB boundary. Fix DMA alignment in case PAGE_SIZE !=
4096. Rename UFSHCD_QUIRK_ALIGN_SG_WITH_PAGE_SIZE into
UFSHCD_QUIRK_4KB_DMA_ALIGNMENT.
