Eric Blake 0d3ef78829 trace: Avoid abuse of amdvi_mmio_read 
hw/i386/trace-events has an amdvi_mmio_read trace that is used for
both normal reads (listing the register name, address, size, and
offset) and for an error case (abusing the register name to show
an error message, the address to show the maximum value supported,
then shoehorning address and size into the size and offset
parameters).  The change from a wide address to a narrower size
parameter could truncate a (rather-large) bogus read attempt, so
it's better to create a separate dedicated trace with correct types,
rather than abusing the trace mechanism.  Broken since its
introduction in commit d29a09c.

[Change trace event argument type from hwaddr to uint64_t since
user-defined types should not be used for trace events.  This fixes a
build failure with LTTng UST.
