x86: mrst: Parse SFI timer table for all timer configs
Penwell has APB timer based watchdog timers, it requires platform code to parse SFI MTMR tables in order to claim its timer. This patch will always parse SFI MTMR regardless of system timer configuration choices. Otherwise, SFI MTMR table may not get parsed if running on Medfield with always-on local APIC timers and constant TSC. Watchdog timer driver will then not get a timer to use.
