5c92fffab2 dma: ti: k3-udma: Update driver to use static endpoint Data
Update driver to use static PSIL endpoint Data instead of DT. This will
allow DT bindings to be in sync with kernel's DT.

Note that this patch breaks networking and OSPI boot as driver changes
are not backward compatible with existing DT. Subsequent commit will
update the DT to make it compatible with updated driver.

53b04c6c09 dma: ti: Add static PSIL endpoint information
Much of PSIL endpoint configuration for a given SoC can be known at
compile time, therefore pass them for platform specific data instead of
DT.

Add per SoC's specific PSIL endpoint data. This is to bring driver in
sync with upstream DT.

ffcc66e8fe dma: ti: add driver to K3 UDMA
The UDMA-P is intended to perform similar (but significantly upgraded) functions
as the packet-oriented DMA used on previous SoC devices. The UDMA-P module
supports the transmission and reception of various packet types.
The UDMA-P also supports acting as both a UTC and UDMA-C for its internal
channels. Channels in the UDMA-P can be configured to be either Packet-Based or
Third-Party channels on a channel by channel basis.

The initial driver supports:
- MEM_TO_MEM (TR mode)
- DEV_TO_MEM (Packet mode)
- MEM_TO_DEV (Packet mode)
