Tested on Radxa E52C:

cpu-code: 35 82
ip-state: 00 04 00 (otp)
ip-state: c0 9e 04 (policy)
remove cpu-map cluster2
fail gpu
fail rkvdec1
fail rkvenc1
fail cpu cpu at 600
fail cpu cpu at 700

and on Radxa ROCK 5C Lite:

cpu-code: 35 82
ip-state: 10 00 00 (otp)
ip-state: 30 9e 04 (policy)
remove cpu-map cluster1
rename cpu-map cluster2
fail gpu
fail rkvdec1
fail rkvenc1
fail cpu cpu at 400
fail cpu cpu at 500
