Subject: [PATCH net-next v1 03/14] net: phy: nxp-c45-tja11xx: remove RX BIST frame counters

RX BIST frame counters can be used only when the PHY is in test mode. In
production mode, the counters will be always read as 0. So, they don't
provide any useful information and are removed from the statistics.
