[PATCH 1/2] gpio: pci-idio-16: Fix port memory offset for get_multiple callback

[William Breathitt Gray]

The ioread8 function expects a memory offset argument. This patch fixes
the ports array to provide the memory addresses of the respective device
I/O registers.

Fixes: 810ebfc5efca ("gpio: pci-idio-16: Implement get_multiple callback")
