Currently the memory controller and master priorities drivers are
enabled in da850.dtsi. For boards for which there are no settings
defined, this makes these drivers emit error messages.

Disable the nodes in da850.dtsi and only enable them for da850-lcdk -
the only board that currently needs them.

Currently the davinci da8xx boards use the mach-davinci aemif code.
Instantiating an aemif node into the DT allows to use the ti-aemif
memory driver and is another step to better DT support.
This change adds an aemif node in the dtsi while retiring the nand_cs3
node. The NAND is now instantiated in the dts as a subnode of the aemif
one along with its pins.

For some devices, the PWMSS is a parent of eCAP and ePWM and provides
the functional clocks for those submodules. The ti,am33xx-ecap and
ti,am33xx-ehrpwm bindings were based on this parent child relationship
where the functional clock would be grabbed from the module's parent.

However, DA850 doesn't have a PWMSS and the eCAP and ePWM provides
their functional clock themselves. Therefore, prefer the new binding
that doesn't assume this parent child relationship.

Switch to use the ti,edma3-tpcc and ti,edma3-tptc binding for the eDMA3.
With the new bindings boards can customize and tweak the DMA channel
priority to match their needs. With the new binding the memcpy is safe
to be used since with the old binding it was not possible for a driver
to know which channel is allowed to be used as non HW triggered channel.
Using the new binding will allow us to reserve PaRAM slots to be used by
the DSP which was not possible before and prevented the da850 boards to be
moved to DT only.

Note that the DMA memcpy is disabled, it can be enabled by reserving
channels for memcpy by adding the following property to the edma node:
ti,edma-memcpy-channels = <20 21>; /* Reserving channel 20 and 21 for memcpy */

DT kernel on da850-evm comes up with garbled UART logs. This is because
of mismatch in actual module clock rate and rate specified(clock-frequency)
in DT blob. kernel should not assume or depend on bootloaders clock
configuration, instead let it find the clock rate at runtime.

Issue discussed here before arriving on this implementation:
