net: emaclite: Don't advertise 1000BASE-T and do auto negotiation
In xemaclite_open() function we are setting the max speed of
emaclite to 100Mb using phy_set_max_speed() function so,
there is no need to write the advertising registers to stop
giga-bit speed and the phy_start() function starts the
auto-negotiation so, there is no need to handle it separately
using advertising registers. Remove the phy_read and phy_write
of advertising registers in xemaclite_open() function.
