gpio: mpc8xxx: Fix a potential double iounmap call in 'mpc8xxx_probe()'
[ Upstream commit 7d65889 ] Commit 76c47d1 ("gpio: mpc8xxx: Add ACPI support") has switched to a managed version when dealing with 'mpc8xxx_gc->regs'. So the corresponding 'iounmap()' call in the error handling path and in the remove should be removed to avoid a double unmap. This also allows some simplification in the probe. All the error handling paths related to managed resources can be direct returns and a NULL check in what remains in the error handling path can be removed.
