Add json file of T-HEAD C9xx series events.

The event idx (raw value) is summary as following:

event id range   | support cpu
 0x01 - 0x06     |  c906,c910,c920
 0x07            |  c906
 0x08 - 0x0a     |  c910,c920
 0x0b - 0x0f     |  c906,c910,c920
 0x10 - 0x1a     |  c910,c920
 0x1b - 0x1c     |  c910,c920 (software defined for all >= 0x1b)
 0x1d - 0x2a     |  c906

The event ids are based on the public document of T-HEAD and cover
the c9xx series.

These events are the max that c9xx series support.
Since T-HEAD let manufacturers decide whether events are usable,
the final support of the perf events is determined by the pmu node
of the soc dtb.

Change from v2:
1. add C906 0x07 events to the instruction.json file
2. fix name for events 0x07 and 0x09 in instruction.json

Example:

This pmu node example can be used on sophgo sg2042 platform (c920) with
mainline OpenSBI.
It should also work on T-HEAD th1520.

For the one use C906 core. Only event 0x01 - 0x07, 0xb - 0xf has known
CSR mapping. The other events do not have known CSR mapping in document
until now.
This pmu node needs to be shorten to adopt c906
