[PATCHv4 1/7] ARM: tegra: Create a DT header defining SWGROUP ID

[Hiroshi Doyu <hdoyu-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>]

Create a header file to define the swgroup IDs used by the IOMMU(SMMU)
binding. "swgroup" is a group of H/W clients which a Tegra SoC
supports. This unique ID can be used to calculate MC_SMMU_<swgroup
name>_ASID_0 register offset and MC_<swgroup name>_HOTRESET_*_0
register bit. This will allow the same header to be used by both
device tree files, and drivers implementing this binding, which
guarantees that the two stay in sync. This also makes device trees
more readable by using names instead of magic numbers. For HOTRESET
bit shifting we need another conversion table, which will come later.

Update:
This is almost same as the previous v3. Just TEGRA_SWGROUP_MAX is
added.
