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.
Fixes: 2c05a0f29f41 ("gpio: ws16c48: Implement and utilize register structures")
