[RESEND] gpio: ws16c48: Fix off-by-one error in WS16C48 resource region extent

[William Breathitt Gray <william.gray@xxxxxxxxxx>]

The WinSystems WS16C48 I/O address region spans offsets 0x0 through 0xA,
which is a total of 11 bytes. Fix the WS16C48_EXTENT define to the
correct value of 11 so that access to necessary device registers is
properly requested in the ws16c48_probe() callback by the
devm_request_region() function call.
