Use devm_kcalloc() in fs_parse_scene_tables() and pcmdev_gain_ctrl_add()
to gain built-in overflow protection, making memory allocation safer when
calculating allocation size compared to explicit multiplication.

This patch adds firmware loading and parsing support for FourSemi audio
amplifiers. The library handles firmware file (*.bin) generated by the
FourSemi tuning tool, which contains:
- Register initialization settings
- DSP effect parameters
- Multi-scene sound effect switching configurations(optional)
The firmware is required for proper initialization and configuration
of FourSemi amplifier devices.
