ipa: rkisp1: agc: Rename maxShutterSpeed to maxFrameDuration
The AGC active state and frame context both contain a variable named
maxShutterSpeed. The variable is used to limit the maximum shutter speed
when computing the exposure time and gains, but stores the maximum frame
duration, not clamped by the sensor's maximum shutter speed. Rename it
to maxFrameDuration.
