TI DaVinci EMAC: Fix incorrect reference to EMAC_CTRL registers.

Browse Source 
The EMAC modules control registers vary as per the version of the
EMAC module. EMAC_CTRL_EWCTL,EMAC_CTRL_EWINTTCNT are available
only on EMAC_VERSION_1. The emac_dump_regs() function accesses
these indiscriminately. This patch fixes the issue.
