[PATCH] phy: Drop unnecessary of_match_device() calls

[PATCH] phy: Drop unnecessary of_match_device() calls

[Rob Herring]

If probe is reached, we've already matched the device and in the case of
DT matching, the struct device_node pointer will be set. Therefore, there
is no need to call of_match_device() in probe.
