Andy Shevchenko 0b3ff17cab gpio: intel-mid: Remove potentially harmful code 
commit 3dbd3212f81b2b410a34a922055e2da792864829 upstream.

The commit d56d6b3d7d ("gpio: langwell: add Intel Merrifield support")
doesn't look at all as a proper support for Intel Merrifield and I dare to say
that it distorts the behaviour of the hardware.

The register map is different on Intel Merrifield, i.e. only 6 out of 8
register have the same purpose but none of them has same location in the
address space. The current case potentially harmful to existing hardware since
it's poking registers on wrong offsets and may set some pin to be GPIO output
when connected hardware doesn't expect such.

Besides the above GPIO and pinctrl on Intel Merrifield have been located in
different IP blocks. The functionality has been extended as well, i.e. added
support of level interrupts, special registers for wake capable sources and
thus, in my opinion, requires a completele separate driver.

If someone wondering the existing gpio-intel-mid.c would be converted to actual
pinctrl (which by the fact it is now), though I wouldn't be a volunteer to do
that.
