phy: miphy365x: Avoid calling of_get_child_count() multiple times

Currently, of_get_child_count() is called in each iteration of the for loop in
miphy365x_xlate(). This patch stores the return value of of_get_child_count()
in miphy_dev->nphys and call of_get_child_count() once in miphy365x_probe().
