At this point in time we can now remove our legacy code and switch to
enabling DM for USB and Ethernet.

ARM: da850-evm: Unify config options with Kconfig
There are two options that are currently whitelisted, but they
are redundant, because there are not necessary since Kconfig options
exist to basically state the same thing.
CONFIG_DIRECT_NOR_BOOT and CONFIG_USE_NOR are both set together and
only used by the da850 when booting from NOR, however the only time
CONFIG_MTD_NOR_FLASH is configured is when booting from NOR. Since
NOR doesn't need SPL, the options for SPL can be moved to a check for
building SPL instead of checking for NOR.
This patch removes the checks for these two config options and unifies
the checks around the Kconfig option of CONFIG_MTD_NOR_FLASH.
Since this board is the only board that uses these two config options,
they can be removed from the whitelist table.

README: davinci: Clarify when SPL is used and the target devices.
The documentation states that SPL is enabled in all config options
for the da850. This incorrect, because devices booting from NOR
do not need the SPL to do the low level initializion because when
booting from NOR, the board is able to execute in place (XIP)
This also clarifies that SPL isn't only used for booting from SPI,
because it is also used for booting from MMC and NAND for those
devices supporting those boot options.
Encapsulate channel configuration in a separate struct so as to ease
resetting of these fields with memset() and also to increase readability
of the code.
soc: ti: k3-ringacc: Add an API to request pair of rings
Add new API k3_ringacc_request_rings_pair() to request pair of rings at
once, as in the most case Rings are used with DMA channels which required
to request pair of rings - one to feed DMA with descriptors (TX/RX FDQ) and
one to receive completions (RX/TX CQ). This will allow to simplify Ringacc
API users.
soc: ti: k3-ringacc: Move state tracking variables under a struct
Move the free, occ, windex and rinfex under a struct.
We can use memset to zero them and it will allow a cleaner way to extend
the variables for duplex rings.
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.
