apalis/colibri_t30: pull-down multiplexed camera input pins saves 100mWColibri_T30_LinuxImageV2.6.1Beta1_20160929Colibri_T20_LinuxImageV2.6.1Beta1_20160929Apalis_T30_LinuxImageV2.6.1Beta1_20160929
Floating pins towards the camera input level-shifter cause it to
consume at least 100mW of power even in idle. This patch fixes this by
configuring pull-downs on all multiplexed camera input pins.
