In 'rt2880_pmx_group_enable' driver is printing an error and returning
-EBUSY if a pin has been already enabled. This begets anoying messages
in the caller when this happens like the following:
rt2880-pinmux pinctrl: pcie is already enabled
mt7621-pci
1e140000.pcie: Error applying setting, reverse things back
To avoid this just print the already enabled message in the pinctrl
driver and return 0 instead to not confuse the user with a real
bad problem.
