Driver doesn't use keyword enum for enum owl_dmadesc_offsets resulting
in warning:

drivers/dma/owl-dma.c:139: warning: cannot understand function prototype:

dma_alloc_coherent() is called with a fixed SZ_2M size, but frees happen
with IOAT_CHUNK_SIZE. Recently, IOAT_CHUNK_SIZE was reduced to 512M but
the allocation did not change. To fix, change to using the
IOAT_CHUNK_SIZE define.

This was caught with the upcoming patchset for converting Intel platforms to the
dma-iommu implementation. It has a warning when the unmapped size differs from
the mapped size.

The jz4780_dma_tx_status() function would check if a channel's cookie
state was set to 'completed', and if not, it would enter the critical
section. However, in that time frame, the jz4780_dma_chan_irq() function
was able to set the cookie to 'completed', and clear the jzchan->vchan
pointer, which was deferenced in the critical section of the first
function.

Fix this race by checking the channel's cookie state after entering the
critical function and not before.

Andy reported that commit 6b41030f ("dmaengine: dmatest:
Restore default for channel") broke his scripts for the case
where "busy" channel is used for configuration with expectation
that run command would do nothing. Instead, behavior was
(unintentionally) changed to treat such case as under-configuration
and progress with defaults, i.e. run command would start a test
with default setting for channel (which would use all channels).

Restore original behavior with tracking status of channel setter
so we can distinguish between misconfigured and under-configured
cases in run command and act accordingly.

Now the K3 UDMA glue layer enable functions perform RMW operation on UDMA
RX/TX RT_CTL registers to set EN bit and enable channel, which is
incorrect, because only EN bit has to be set in those registers to enable
channel (all other bits should be cleared 0).
More over, this causes issues when bootloader leaves UDMA channel RX/TX
RT_CTL registers in incorrect state - TDOWN bit set, for example. As
result, UDMA channel will just perform teardown right after it's enabled.

Hence, fix it by writing correct values (EN=1) directly in UDMA channel
RX/TX RT_CTL registers in k3_udma_glue_enable_tx/rx_chn() functions.
