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. For cases where struct device pointer `dev` is not available, NULL can be passed to vchiq_log_error() to log to dynamic debug using pr_debug().

The log category is dictated by enum vchiq_log_category which will become the part of the trace string format that will be logged to dynamic debug (for grep). All the vchiq_log_trace() calls are adjusted to use the modified wrapper. vchiq_log_dump_mem() doesn't has access to struct device pointer. It will be logged to dynamic debug by passing NULL to vchiq_log_trace() which shall log it using pr_debug().
