drivers: net: cpsw: Fix TX_IN_SEL offset
The TX_IN_SEL offset for the CPSW_PORT/TX_IN_CTL register was
incorrect. This caused the Dual MAC mode to never get set when
it should. It also caused possible unintentional setting of a
bit in the CPSW_PORT/TX_BLKS_REM register.
The purpose of setting the Dual MAC mode for this register is to:
"... allow packets from both ethernet ports to be written into
the FIFO without one port starving the other port."
