To avoid the duplication of CLK ID defines both in boot/dts and kernel
source, use the one from the DT header file and get rid of own
definitions in kernel source.

There are some cases that IOVA allocation and mapping have to be done
seperately, especially for perf optimization reasons. This patch
allows client modules to {alloc,free} IOVA space without backing up
actual pages for that area.

Introduce a helper function, dma_map_linear(_attrs)() to create IOVA
linear map, where IOVA and kernel virtual addresses are mapped at the
same address linearly. This is useful to support legacy device drivers
which expects no IOMMU.

dev_dbg_reatelimited() without DEBUG printed 217078 callbacks

With CONFIG_DYNAMIC_DEBUG, the print should be configured as expected.
