scsi: ufs: core: Add UFSHCD_QUIRK_CUSTOM_CRYPTO_PROFILE
[ Upstream commit c2a90eee29f41630225c9a64d26c425e1d50b401 ]
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.
