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.
