commit e3af9f7c upstream.

On the CP modules we found on Armada 7K/8K, many IP block actually also
need a "functional" clock (from the bus). This patch add them which allows
to fix some issues hanging the kernel:

If Ethernet and sdhci driver are built as modules and sdhci was loaded
first then the kernel hang.

Fixes: bb16ea17 ("mmc: sdhci-xenon: Fix clock resource by adding an optional bus clock")
