serial: 8250_exar: Don't remove GPIO device on suspend

Browse Source 
[ Upstream commit 73b5a5c00be39e23b194bad10e1ea8bb73eee176 ]

It seems a copy&paste mistake that suspend callback removes the GPIO
device. There is no counterpart of this action, means once suspended
there is no more GPIO device available untile full unbind-bind cycle
is performed. Remove suspicious GPIO device removal in suspend.

Fixes: d0aeaa83f0b0 ("serial: exar: split out the exar code from 8250_pci")
