falco: peppy: slippy: mark LPC_CLKRUN_L as open drain

Browse Source 
The LPC_CLKRUN_L signal on these boards has an external pull
up to the correct PCH rail. Therefore, configure the pin
controlling LPC_CLKRUN_L as open drain.

BUG=chrome-os-partner:19811
BUG=chrome-os-partner:20331
BRANCH=None
TEST=Built and flashed. Interrogated GPIOODR register for port M:
     > rw 0x4006350c
     read 0x4006350c = 0x00000004
