[PATCH v6 07/29] hw/intc/aspeed: Add object type name to trace events for better debugging

[Jamin Lin via <qemu-devel@nongnu.org>]

Currently, these trace events only refer to INTC. To simplify the INTC model,
both INTC(CPU Die) and INTCIO(IO Die) will share the same helper functions.

However, it is difficult to recognize whether these trace events are comes from
INTC or INTCIO. To make these trace events more readable, adds object type name
to the INTC trace events.
Update trace events to include the "name" field for better identification.
