gpio: remove some legacy comments in build files

The build files for drivers/gpio has some wording and comments
about the directory being reserved exclusively for GPIO expanders
(according to the gpio.txt file these are on external busses) and
this has been false for some time. We already have PL061 and
Xilinx drivers which are in silicon and now I'm moving more
silicon drivers here, so delete this and reword it a bit.

This enables GPIO support through the generic GPIO library.
You only need to enable this, if you also want to enable
one or more of the GPIO expansion card drivers below.

Kernel drivers may also request that a particular GPIO be
exported to userspace; this can be useful when debugging.
