The QCS8300 platform has LLCC(Last Level Cache Controller) as the system
cache controller. Add binding, configuration and device tree node to
support this. There is an errata to get the number of the banks of the
LLCC on QCS8300 platform, hardcode it as a workaround.

Patch3 depends on below patch series:
