It's a bit moot here since the shift is 0, but I thought the mask
normally included the shift already...
#define CP_MQD_BASE_ADDR__BASE_ADDR_MASK 0xfffffffc
#define CP_MQD_BASE_ADDR__BASE_ADDR__SHIFT 0x2
#define CP_HPD_EOP_CONTROL__PEND_SIG_SEM_MASK 0x80000000
#define CP_HPD_EOP_CONTROL__PEND_SIG_SEM__SHIFT 0x1f
etc.
