daisy: Re-read suspend gpio when asked for chipset state
The SUSPEND_L GPIO is marked interruptable, but this apparently
does not work, and the gaia_suspend_event() function is not updated as expected.
As a workaround, check the GPIO value on ever call to
chipset_in_state().
BUG=chrome-os-partner:11285
TEST=manal
Using new 'power' command check that the state updates when the AP
is in suspend from 'on' to 'suspend'.
