This fixes a Kconfig issue with UM: when I made GPIOLIB
available to all archs, that included UM, but the OF part
of GPIOLIB requires HAS_IOMEM, so we add HAS_IOMEM as a
dependency to OF_GPIO.
This in turn exposed the fact that a few GPIO drivers were
implicitly assuming OF_GPIO as their dependency but instead
depended on OF alone (the typical problem being a pointer
inside gpio_chip not existing unless OF_GPIO is selected)
and then UM would fail to compile with these drivers
instead. Then I lost patience and made any GPIO driver
depending on just OF depend on OF_GPIO instead, that is
certainly what they meant and the only thing that makes
sense anyway. GPIO with just OF but !OF_GPIO does not make
sense.
Also a fix for the max730x driver data pointer, and a minor
comment fix for the GPIO tools.

Pull GPIO fixes from Linus Walleij:
"Here are a few GPIO fixes for v4.8.
I was expecting some fallout from the new chardev rework but nothing
like that turned up att all. Instead a Kconfig confusion that I think
I have finally nailed, then some ordinary driver noise and trivia.
This fixes a Kconfig issue with UM: when I made GPIOLIB available to
all archs, that included UM, but the OF part of GPIOLIB requires
HAS_IOMEM, so we add HAS_IOMEM as a dependency to OF_GPIO.
This in turn exposed the fact that a few GPIO drivers were implicitly
assuming OF_GPIO as their dependency but instead depended on OF alone
(the typical problem being a pointer inside gpio_chip not existing

these drivers instead. Then I lost patience and made any GPIO driver
depending on just OF depend on OF_GPIO instead, that is certainly what
