lid_switch: allow to specify several lid GPIOs
Add a X-macro CONFIG_LID_SWITCH_GPIO_LIST to be able to optionally
specify more than one GPIO to check to find out whether the lid is open.
By default, use GPIO_LID_OPEN as before.

BRANCH=smaug
BUG=chrome-os-partner:42110
TEST=on Smaug EVT2, define CONFIG_LID_SWITCH_GPIO_LIST as
LID_GPIO(GPIO_LID_OPEN) LID_GPIO(GPIO_BASE_PRES_L) and play with magnets
and the genuine lid, check we get the right "lid open" / "lid close"
messages on the console.
