Sergio Paracuellos 0b44524963 pinctrl: ralink: rt2880: avoid to error in calls is pin is already enabled 
[ Upstream commit eb367d875f94a228c17c8538e3f2efcf2eb07ead ]

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.
