Add the missing CPU topology/capacity information and the cpufreq nodes, so we can have CPU frequency scaling and the scheduler has the information it needs to make the correct decisions. As with t8103, boost states are commented out pending PSCI/etc support for deep sleep states. Reviewed-by: Sven Peter <sven@svenpeter.dev> Signed-off-by: Hector Martin <marcan@marcan.st>
