Google/Snow: Revise bootblock initialization.

It's fine to always start timer even in suspend/resume mode, so we can
    move the timer_start() back to the very beginning of boot procedure.
    That provides more precise boot time information.

With that timer change, the wake up state test procedure can be simplified.

Verified by building and booting firmware image on Google/Snow successfully,
    and then suspend-resume without problem (suspend_stress_test).
