Subject: [PATCH v1] x86/platform/intel-mid: Correct MSI for watchdog device

The interrupt line used for watchdog is 12 according to the official
Intel Edison BSP code.

And indeed after fixing it we start getting an interrupt and thus:
[  191.699951] Kernel panic - not syncing: Kernel Watchdog

Fixes: 78a3bb9e408b ("x86: intel-mid: add watchdog platform code for Merrifield")
