Subject: [RFC v1 10/11] media: platform: neoisp: Add debugfs support
Add debugfs entries to dump ISP registers, and some internal memory
regions used to store Vignetting, DRC global and DRC local coefficients.
Debug mode is activated with the `enable_debugfs` module's parameter, to
avoid runtime suspend which blocks register access when IP is not active,
so we can capture an ISP snapshot after a frame is decoded.
