Use ring_idx to pair rings. ring_idx will be same as tx flow_id for all non-negative flow_ids. For negative flow_ids, ring_idx will be tchan->id added with bchan_cnt.

A follow-up to commit 842fb5de424e
("drivers: use devfdt_get_addr_size_index_ptr when cast to pointer")
and commit 320a1938b6f7
("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.

The PSIL endpoint data for J721E currently covers only the MCU domain CPSW0 instance. Add the data for the MAIN domain CPSW0 as well to allow the MAIN domain Ethernet ports to be usable on any platform using J721E SoC. Additionally, since J721E's PSIL endpoint data is applicable to J7200 SoC as well, the MAIN CPSW0 instance on J7200 will also be usable now.

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()
This fixes occasional TFTP Failures seen when downloading multiple files
one after the other on AM64/AM62 SoCs.
