via_wdt: fix critical boot hang due to unnamed resource allocation

In the Linux kernel, the following vulnerability has been resolved:

via_wdt: fix critical boot hang due to unnamed resource allocation

The VIA watchdog driver uses allocate_resource() to reserve a MMIO
region for the watchdog control register. However, the allocated
resource was not given a name, which causes the kernel resource tree
to contain an entry marked as "<BAD>" under /proc/iomem on x86
platforms.

During boot, this unnamed resource can lead to a critical hang because
subsequent resource lookups and conflict checks fail to handle the
invalid entry properly.
