If ZSL is enabled, the HAL might automatically force a lower fps
(depending on the current resolution). This causes problems if the
normal fps range is not restored before changing configuration
(e.g. changing resolution, enabling HDR, switching to video mode).
When this happens, the sensor gets stuck at low fps, the preview
becomes dark and an invalid fps preview range might get selected,
leading to a crash. Disable ZSL to prevent all these issues.
