To categorise, enum vchiq_log_category has been introduced, which will become the part of the error string format that will be logged to dynamic debug (for grep). All the vchiq_log_error() calls are adjusted to use the dynamic debug wrapper. vchiq_loud_error_*() has been removed as a part of this patch and replaced with dev_err (so that they directly end up in kernel log, even if dynamic debug isn't enabled), which serves the purpose.
