media: video: tegra: sh532u: Focuser range tuning support
Support for get/set capabilities added. Focuser code has a way to
calibrate itself that results in determination of optimal working
range. This along with actual range from device ROM are returned
to the caller. Focuser has the macro at lower end and infinity at
farther end of the range, which are reversed to the user level to
keep the inf/macro positions to be consistent. Focuser range
translation is taken out.
