[coreboot] Rangeley reset

[Wen Wang]

Hello,

Has anybody tested reset signal (PMU_RESETBUTTON_B) on Rangeley/Avoton? The
board seems to shut down after asserting the signal (pushing the reset
button). I turn on an LED in early_mainboard_romstage_entry(). The LED was
not on indicating the function was not executed. Below is what printed out
on console after reset:

For cold boot, it will continue to spit out boot messages.

Thanks!
