Kerneldoc expects struct properties to be documented using the syntax
'@.*: ', but no ':' has been provided in 'struct it87_gpio's
header.  Add them to stop confusing kerneldoc.

Fixes the following W=1 warnings:

 drivers/gpio/gpio-it87.c:69: warning: Function parameter or member 'chip' not described in 'it87_gpio'

This was tested on actual hardware and found to work fine, but currently
the official specifications of this chip could not be obtained to
confirm the numbers.

The DIO connector on the WAFER-945GSE is interfaced to GPIO ports
on the ITE IT8718F Super I/O chipset. From the datasheet of ITE IT8718F,
the GPIO interface is identical to IT8728, so just add it
to the same case as the other chip.

These structures are only used to copy into other structures, so declare
them as const.
