net: phy: bcm7xxx: Fix shadow mode 2 disabling

BugLink: https://bugs.launchpad.net/bugs/1878232

commit 50d89980 upstream.

The clear and set masks in the call to phy_set_clr_bits() called from
bcm7xxx_config_init() are inverted. We need to fix this by swapping the two
arguments, that is, set 0 bits, but clear the shade mode 2 enable bit.
