Subject: [PATCH 1/3] msm: iommu: Add bus clocks to platform data

Add the IOMMU bus clock and the IOMMU bus interconnect
clocks to the platform data for an IOMMU device. These
clocks are needed to access the IOMMU registers.

Signed-off-by: Stepan Moskovchenko <stepanm@...eaurora.org>

Please hold off on this until the clock driver is in.
