The user can set event and counter in cmdline and the driver need to parse
it using 'config' attr value. This will add macro definitions to avoid
hard-code in driver.

Can you move this patch earlier, please, so that the imx95 support can use
these new definitions immediately?

Yes, I will try it in next version.
