Subject: [PATCH] perf vendor events arm64: Arm Cortex-A78C and X1C

Add PMU events for the Arm Cortex-A78C and Arm Cortex-X1C CPUs.

Events for Arm Cortex-A78C match those for Arm Cortex-A78.
Events for Arm Cortex-X1C match those for Arm Cortex- X1.

As such, this is just a mapfile change.

Main ID Register (MIDR) and event data is sourced from the corresponding
Arm Technical Reference Manuals:

Arm Cortex-A78C
https://developer.arm.com/documentation/102226/

Arm Cortex-X1C
https://developer.arm.com/documentation/101968/
