mb/google/poppy/variants/nami: Invert polarity of EMR_GARAGE_DET# 

This gpio should be active low, but is not currently configured that way.
Changing gpio configuration to reflect that.

BUG=b:73121017, b:77941823
BRANCH=None
TEST=iotools mmio_read32 0xfdae0588 (GPP_E1) Make sure that when pen
     is ejected, gpio is low and when pen is inserted, gpio is high.
     Also tested that wake upon pen eject is working.
