scsi: ufs: core: Add UFSHCD_QUIRK_CUSTOM_CRYPTO_PROFILE
Add UFSHCD_QUIRK_CUSTOM_CRYPTO_PROFILE which lets UFS host drivers
initialize the blk_crypto_profile themselves rather than have it be
initialized by ufshcd-core according to the UFSHCI standard. This is
needed to support inline encryption on the "Exynos" UFS controller which
has a nonstandard interface.
