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.

We're planning to remove the gpiochip_add() function to swith
to gpiochip_add_data() with NULL for data argument.

As we want gpio_chip .get() calls to be able to return negative
error codes and propagate to drivers, we need to go over all
drivers and make sure their return values are clamped to [0,1].
We do this by using the ret = !!(val) design pattern.

Move the m68k ColdFire platform support code directory to be with the
existing m68k platforms. Although the ColdFire is not a platform as such,
we have always kept all its support together. No reason to change that
as this time.
