Subject: [PATCH V3 1/3] ufs: ufs-qcom: Update esi_vec_mask for HW major version >= 6

From: "Bao D. Nguyen" <quic_nguyenb@...cinc.com>

The MCQ feature and ESI are supported by all Qualcomm UFS controller
versions 6 and above.

Therefore, update the ESI vector mask in the UFS_MEM_CFG3 register
for platforms with major version number of 6 or higher.
