Add reset-gpio support. Without reset's deassertion during ak8975_power_on(), driver's probe fails on ak8975_who_i_am() while checking for device identity for AK09911 chip. AK09911 has an active low reset gpio to handle register's reset. AK09911 datasheet says that, if not used, reset pin should be connected to VID. This patch emulates this situation.
