[SCSI] mvsas: Remove unused macros, variables and functions 

Remove unused macros: VSR_PHY_VS0, VSR_PHY_VS1, MVS_SLOTS,
	MVS_CAN_QUEUE, MVS_MSI, SG_MX, _MV_DUMP, MV_DISABLE_NCQ
Remove unused variables for mvs_info: irq, exp_req, cmd_size
Remove unused functions: mvs_get_sas_addr, mvs_hexdump,
	mvs_hba_sb_dump, mvs_hab_memory_dump, mvs_hba_cq_dump
