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.
