ACPI: watchdog: Fix gas->access_width usage
ACPI Generic Address Structure (GAS) access_width field is not in bytes
as the driver seems to expect in few places so fix this by using the
newly introduced macro ACPI_ACCESS_BYTE_WIDTH().
Fixes: b1abf6fc4982 ("ACPI / watchdog: Fix off-by-one error at resource assignment")
Fixes: 058dfc767008 ("ACPI / watchdog: Add support for WDAT hardware watchdog")
