ACPI: watchdog: Fix gas->access_width usage

BugLink: https://bugs.launchpad.net/bugs/1866333
commit 2ba33a4e9e22ac4dda928d3e9b5978a3a2ded4e0 upstream.

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().
