I found it strange that the vendor specific subdirectories were unconditionally
added. Everything in these directories obviously depends on the specific Kconfig
option. This series cleans this up by making the directory itself depend on
the respective option which looks more natural to me.
I must confess that I am too lazy to find a good solution for the "arm/"
directory, so I left it as is.
Regards,
Eike

Changes in v2:
- clean up subdirectory Makefiles to use obj-y now
- add arm/arm-smmu-v3 and iommufd patches
