[PATCH net-next 05/13] net: mvpp2: do not set the XLG MAC in reset when disabling a port

[Antoine Tenart]

This patch prevents the PPv2 driver to put the XPCS in reset while
disabling a port. A port and the XPCS are two different blocks, and a
port can be used without the XPCS. Their configuration should be done
separately, which is already the case in the driver except for this one
example.
