net: phy: mscc: configure both RX and TX internal delays for RGMII

Browse source

The driver appears to be secretly enabling the RX clock skew
irrespective of PHY interface type, which is generally considered a big
no-no.

Make them configurable instead, and add TX internal delays when
necessary too.

While at it, configure a more canonical clock skew of 2.0 nanoseconds
than the current default of 1.1 ns.
