Already from family 8000 and up the dash (bits 0-1) no longer exist and the step (until 8000 bits 2-3) consists of also the dash bits. To do this remove the CSR_HW_REV_STEP and the CSR_HW_REV_DASH macros, replace them with CSR_HW_REV_STEP_DASH and add hw_rev_step into the trans struct. In addition remove the CSR_HW_IF_CONFIG_REG_MSK_MAC_STEP and CSR_HW_IF_CONFIG_REG_MSK_MAC_DASH macros and create a new macro combining the 2 (this way we don't need shifting or anything else.)
