dmaengine: axi-dmac: add support for reading bus attributes from registers

Starting with core version 4.3.a the DMA bus attributes can (and should) be
read from the INTERFACE_DESCRIPTION (0x10) register.

For older core versions, this will still need to be provided from the
device-tree.

The bus-type values are identical to the ones stored in the device-trees,
so we just need to read them. Bus-width values are stored in log2 values,
so we just need to use them as shift values to make them equivalent to the
current format.

dmaengine: axi-dmac: wrap channel parameter adjust into function

The channel parameters (which are read from the device-tree) are adjusted
for the DMAEngine framework in the axi_dmac_parse_chan_dt() function, after
they are read from the device-tree.

When we want to read these from registers, we will need to use the same
logic, so this change splits the logic into a separate function.

Pull dmaengine updates from Vinod Koul:
"This time we have a bunch of core changes to support dynamic channels,
hotplug of controllers, new apis for metadata ops etc along with new
drivers for Intel data accelerators, TI K3 UDMA, PLX DMA engine and
hisilicon Kunpeng DMA engine. Also usual assorted updates to drivers.

Core:
- Support for dynamic channels
- Removal of various slave wrappers
- Make few slave request APIs as private to dmaengine
- Symlinks between channels and slaves
- Support for hotplug of controllers
- Support for metadata_ops for dma_async_tx_descriptor
- Reporting DMA cached data amount
- Virtual dma channel locking updates

New drivers/device/feature support support:
- Driver for Intel data accelerators
- Driver for TI K3 UDMA
- Driver for PLX DMA engine
- Driver for hisilicon Kunpeng DMA engine
- Support for eDMA support for QorIQ LS1028A in fsl edma driver
- Support for cyclic dma in sun4i driver
- Support for X1830 in JZ4780 driver"
