Currently, the allocation of DMA channel[0] for memcpy is happening
in udma_transfer() for every transfer, which leads to a huge overhead
for each transfer, especially in case of nand page reads. So, move this
allocation to udma_probe(), as a result, the allocation is done once
during probe.
Introduce udma_remove() for the cleanup of allocated channel during
probe.

The udma_probe() function was placed above many important APIs
related to bcdma, pktdma, which restricts these APIs to be accessed
during probe. So, move udma_probe() below all of them.

Buffers must not have an unclean cache before being used for DMA - a
pending write-back may corrupt the next dev-to-mem transfer otherwise.
This was consistently noticeable during long TFTP transfers, when an ARP
request is answered by U-Boot in the middle of the transfer:
As U-Boot's arp_receive() reuses the receive buffer to prepare its
reply packet, the beginning of one of the next incoming TFTP packets
is overwritten by the ARP reply. The corrupted packet is ignored, but
the TFTP transfer stalls for a few seconds until a timeout is detected
and a retransmit is triggered.

In udma_probe() the return value of setup_resources() is stored in the
u32 "ch_count" member of "struct udma_dev", due to which any negative
return value which indicates an error is masked.
Fix this by storing the return value of setup_resources() in the already
declared integer variable "ret", followed by assigning it to the "ch_count"
member of "struct udma_dev" in case of no error.
While at it, change the "return ret" at the end of udma_probe() to a
"return 0", to explicitly indicate that probe was successful.

A follow-up to commit 842fb5de42
("drivers: use devfdt_get_addr_size_index_ptr when cast to pointer")
and commit 320a1938b6
("drivers: use devfdt_get_addr_index_ptr when cast to pointer").
In addition to using the *_ptr variants of these functions where the
address is cast to a pointer, this also changes devfdt_get_addr_*() to
dev_read_addr_*() in a few places. Some variable and field types are
changed from fdt_addr_t or phys_addr_t to void* where the cast was
happening later.
This patch fixes a number of compile warnings when building a 32bit
U-Boot with CONFIG_PHYS_64BIT=y. In some places, it also fixes error
handling where the return value of dev_read_addr() etc. was checked for
NULL instead of FDT_ADDR_T_NONE.

Setting RX flow error handling will stall the channel until descriptors
are available to move RX data. Setting this bit causes issues when
tearing down ethernet DMA channel at the end of TFTP transfer as
unrelated network packets can cause teardown to stall indefinitely waiting
for driver to queue add more desc leading to channel hang with error
logs:
udma_stop_dev2mem TIMEOUT !
udma_stop_dev2mem: peer not stopped TIMEOUT !
udma_stop_dev2mem TIMEOUT !
Fix this by clearing rx_error_handling similar to how its done for UDMA
as part of udma_alloc_rchan_sci_req()
