MIPS: pci-rt2880: remove unneeded locks
Mirror pci-rt3883 fix from commit
e5067c718b3a ("MIPS: pci-rt3883:
Remove odd locking in PCI config space access code"). pci-rt2880 shares
the driver layout with pci-rt3883 and the same reasons apply.
Caller (generic PCI code) already does proper locking, so no need to add
another one here. Local PCI read/write functions are never called
simultaneously, also they do not require synchronization with the PCI
controller ops, since they are used before the controller registration.
