Move vchiq_log_trace() custom logging wrapper based on printk
to use dynamic 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.
