net: dsa: vsc73xx: allow phy resetting
Resetting the VSC73xx PHY was problematic because the MDIO bus, without
a busy check, read and wrote incorrect register values.
My investigation indicates that resetting the PHY only triggers changes
in configuration. However, improper register values written earlier
were only exposed after a soft reset.
The reset itself wasn't the issue; rather, the problem stemmed from
incorrect read and write operations.
A 'soft_reset' can now proceed normally. There are no reasons to keep
the VSC73xx from being reset.
This commit removes the reset blockade in the 'vsc73xx_phy_write'
function.
