The patchset fixes some warnings reported by the kernel during boot.
The cache size info is from Processor_Datasheet_v2XX.pdf [1], Section 2.2.1 Master Processor.
The cache line size and the set-associative info are from Cortex-A53 Documentation [2].
From the doc, it can be concluded that L1 i-cache is 4-way assoc, L1 d-cache is 2-way assoc and L2 cache is 16-way assoc. Calculate the dts props accordingly.
Also, to use KVM's VGIC code, GICH, GICV registers spaces and maintenance IRQ are added to the dts with verification.

Best regards,
May someone apply this patchset to their tree so that it can land in stable at the end? This is a fix, not adding new functionalities. It's been 2 weeks already.
