This reverts commit 7144afd025 ("dmaengine: fsl-edma: add i.mx7ulp
edma2 version support") as this fails to build with module option due to
usage of of_irq_count() which is not an exported symbol as kernel
drivers are *not* expected to use it (rightly so).

Add edma2 for i.mx7ulp by version v3, since v2 has already
been used by mcf-edma.
The big changes based on v1 are belows:
1. only one dmamux.
2. another clock dma_clk except dmamux clk.
3. 16 independent interrupts instead of only one interrupt for
all channels.

There are some differences between vf610 and next i.mx7ulp. Put such
differences into static driver data for distinguishing easily at
driver level. Change mcf-edma accordingly.

This mapping needs to be created in order for slave dma transfers
to work on systems with SMMU. The implementation mostly mimics the
one in pl330 dma driver, authored by Robin Murphy.

dma_slave_config direction was marked as deprecated quite some
time back, remove the usage from this driver so that the field
can be removed

This patch fixes macros to use BIT() and GENMASK(), removing
also some unneeded.

This patch adds configurable registers (using __iomem addresses)
to allow the use of fsl-edma-common code with slightly different
edma module versions, as Vybrid (v1) and ColdFire (v2) are.

This patch adds a new fsl-edma-common module to allow new
mcf-edma module code to use most of the fsl-edma code.
