The bitmasks for EMAC_PORT_DISABLE and EMAC_PORT_FORWARD r30 commands are
wrong in the driver.

Update the bitmasks of these commands to the correct ones as used by the
ICSSG firmware. These bitmasks are backwards compatible and work with
any ICSSG firmware version.

Changes from v2 to v3:
*) Updated the commit message mentioning that the patch is infact backwards
   compatible after testing the patch with multiple firmwares. The patch works
   with both old and new ICSSG firmwares.
*) Rebased on latest net/main.

Changes from v1 to v2:
*) Added firmware version in commit message as asked by Ravi.
*) Mentioned in commit message that the patch is not backwards compatible
   as asked by Andrew.
