Subject: [PATCH V3 3/5] scsi: ufs: core: Remove unused ufshcd_res_info structure

From: Nitin Rawat <quic_nitirawa@...cinc.com>

Remove the ufshcd_res_info structure and associated enum ufshcd_res
definitions from the UFS host controller header. These were previously
used for MCQ resource mapping but are no longer needed following recent
refactoring to use direct base addresses instead of multiple separate
resource regions
