net ep93xx mii: do not supress MII preamble transmission
PHY like the ks8721bl used on the edb9302 and similar evaluation boards will initially not respond to the ep93xx_phy_read/write functions when the MII-preamble is supressed. The supression is switched on by default and must be switched off by clearing bit 8, see also EP93xx Users guide. Removing the orphaned MII_SUPPRESS_PREAMBLE config option, note: setting MII_SUPPRESS_PREAMBLE would actually enable the preamble transmission.
