Currently, there is no dependency between kgsl driver probe and smmu
driver probe, this results in issues in case smmu driver probe is not
done before kgsl driver probe. To ensure kgsl driver probe/bind
happens only post smmu driver probe, add kgsl MMU and CBs as a component
device.
As CB nodes contain "iommus" property, fw_devlink ensures that CBs
are probed only after corresponding supplier (smmu driver) probe is
done. Adding CBs as a component device ensures master bind (adreno_bind)
is called only once all components are probed. So adding CBs as component
device ensures kgsl probe/bind are done only post smmu driver probe.

For LPAC context ttbr0 base address will be having pagetable
base address and ASID field. During fault process identification
pagetable base address comparison will fail with ttbr0. Hence mask
ASID field from the ttbr0 to correctly match it with pagetable base.

ASID is used by SMMU in TLB invalidation path, query ASID
number from the MMU driver and program it while updating
the page table base address.

Currently gpuaddr_in_range() accepts only the gpuaddr & returns
true if it lies in valid range. But this does not mean that the
entire buffer is within range.
Modify the function to accept size as a parameter and check that
both starting & ending points of buffer lie within mmu range.
