This includes the following (skipped due to lines) diff:
* 0x14100 0x0100 ARMv8 events
+ * 0x14200 0x0020 ARM DMC-620 clkdiv2 events
+ * 0x14220 0x0080 ARM DMC-620 clk events
+ * 0x14300 0x0100 ARM CMN-600 events
Not enough space was allocated for Armv8 events as it goes up to 0x3ff
in Armv8 (and beyond in later versions of the architecture). Downstream
we extend this range in CheriBSD as required for Morello’s events.
Please relocate these new events well past the end of the existing
Armv8 events so the space can remain contiguous.
Should this be 0x3ff then as well btw?

Looking more closely it seems from ARMv8.1 onwards it goes up to 0xFFFF
if I read 'Table D8-7 Allocation of the PMU event number space' of ARM
DDI 0487H.a correctly?
So we should bump this to 0x15000 at least and use that space for
other events?
I wonder if anyone will do the 700 soon as well?
