Allwinner aren't the only ones using T-Head CPUs that the previous
m*id pmu detection code would have matched on. I think the first three
files below will also need to be updated:

rg -l "thead,c[0-9]*\b[^-]" arch/riscv/boot/dts/
arch/riscv/boot/dts/sophgo/sg2042-cpus.dtsi
arch/riscv/boot/dts/sophgo/cv1800b.dtsi
arch/riscv/boot/dts/thead/th1520.dtsi
arch/riscv/boot/dts/allwinner/sun20i-d1s.dtsi

Cheers,
Conor.
