net: phy: export phy_error and phy_trigger_machine
[ Upstream commit 293e9a3d950dfebc76d9fa6931e6f91ef856b9ab ]
These functions are currently used by phy_interrupt() to either signal
an error condition or to trigger the link state machine. In an attempt
to actually support shared PHY IRQs, export these two functions so that
the actual PHY drivers can use them.
