m68k/gpio: remove arch specific sysfs bus device
The ColdFire architecture specific gpio support code registers a sysfs bus device named "gpio". This clashes with the new generic API device added in commit 3c702e99 ("gpio: add a userspace chardev ABI for GPIOs"). The old ColdFire sysfs gpio device was never used for anything specific, and no links or other nodes were created under it. The new API sysfs gpio device has all the same default sysfs links (device, drivers, etc) and they are properly populated. Remove the old ColdFire sysfs gpio registration.
