The first 10 patches add a new function, of_get_cpu_hwid(), which parses
CPU DT node 'reg' property, and then use it to replace all the open
coded versions of parsing CPU node 'reg' properties.

The last 2 patches add support for populating the cacheinfo 'id' on DT
platforms. The minimum associated CPU hwid is used for the id. The id is
optional, but necessary for resctrl which is being adapted for Arm MPAM.

Tested on arm64. Compile tested on arm, x86 and powerpc.

On ARM and ARM64:

Tested-by: Florian Fainelli <f.fainelli@gmail.com>

lscpu -C continues to work on ARM64 as before with cache properties provided in the FDT.
