media: dw9807-vcm: Add support for DW9817 bidirectional VCM driver

The DW9817 is effectively the same as DW9807 from a programming
interface, however it drives +/-100mA instead of 0-100mA. This means
that the power on ramp needs to take the lens from the midpoint, and
power off return it there. It also changes the default position for
the module.
