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.
