As axidma(4) does not support busdma(9) then add local cache flushes,
and map descriptors using default memory attribute (cacheable type).
This fixes operation on Codasip X730.

The xae(9) driver expects that the "memory-region" property is always
provided in its DTS node, but this is not a case for every platform.
If the property is not provided, then no restriction on buffer location
is in place and busdma backend could be used.
Since the Xilinx AXI DMA engine driver does not support busdma(9), then
allocate some memory for buffers manually, so we don't panic.
This fixes operation on Codasip A730.
- add compat table and a string for an older IP
- name driver properly
- depend on ofw_spibus
- add missing ofw_bus_get_node() method
- connect to GENERIC (similar to other Xilinx IP)
Tested on Codasip A730.
Change 4787572d05 made if_alloc_domain() never fail, then also do the
wrappers if_alloc(), if_alloc_dev(), and if_gethandle().
No functional change intended.

riscv cores.
GFE cores come with standard DTS file that lacks standard 'dmas ='
property, which means xae(4) could not find a DMA controller to use.
The 'dmas' property could not be added to the DTS file because the
ethernet controller and DMA engine parts in Linux are implemented
in a single driver.
Instead of 'dmas' property the standard Xilinx 'axistream-connected'
property is provided, so fallback to use it instead.

XCHAN_CAP_BOUNCE.
The only application that uses bounce buffering for now is the Government
Furnished Equipment (GFE) P2's dma core (AXIDMA) with its own dedicated
cacheless bounce buffer.

As cs is stored in a uint32_t, use the last bit to store the
active high flag as it's unlikely that we will have that much CS.
