So far all the u-boot specific properties for both r5 and a53 are
placed in k3-am654-base-board-u-boot.dtsi. But there are few a53
nodes that should be updated but doesn't belong to r5. So create a
separate r5 specific u-boot dtsi.

Because of fundamental interface issues in am65x pg1, only the
initial sdhci1 node at 25 MHz was added in the u-boot.dtsi
from which both the base-board.dts and r5-base-board.dts
inherit the node. Move the node out to k3-am65-main.dtsi
where it belongs and add the board specific properties
in base-board.dts and r5-base-board.dts
This ensures dts compatibility with the kernel dts in the
base-board.dts and enables the SD card interface at 50 MHz
and High Speed mode
While we are here, also fix the main_mmc0_pins_default
property to be included and inherit from the base-board.dts
instead of the u-boot.dtsi

In 1 bit mode OSPI can work at upto 50MHz, this provides better write
performance. Therefore increase frequency from 40MHz to 50MHz

wkup_vtm populates only 1 power-domain cell in it's node. But the
power-domain cell are defined as 2. Due to this the following warning
comes during build:
arch/arm/dts/k3-am654-r5-base-board.dtb: Warning (power_domains_property):
/interconnect@100000/interconnect@28380000/interconnect@42040000/
wkup_vtm@42050000:power-domains: property size (8) too small for cell size 2
Fix this by updating the power-domain cells.

enable the node under SPL. This will enable the AVS class 0 support on

Add VTM node for voltage and thermal management. For u-boot, this is needed
for supporting AVS class 0, as the efuse values for the OPPs are stored
under the VTM.

The current configuration of DDR on AM654 base board is for 1600MTs but
the file name is specified as k3-am654-base-board-ddr4-1600MHz.dtsi.
Since 1600MHz is misleading, rename it to
k3-am654-base-board-ddr4-1600MTs.dtsi

Although we currently use the MAIN_UART0 for R5 SPL console output there
are cases where we require access to the MCU_UART0 as well for example in
case of UART-based Y-Modem boot. To support these scenarios add related
DTS definitions to be able to use that UART early on.

To enable the use of an EEPROM-based board detection scheme we need to
be able to access the I2C bus associated with the EEPROMs across all
3 stages of U-Boot: R5 SPL, A53 SPL, and A53 U-Boot (proper). So go
ahead and add/update the wkup_i2c0 peripheral module DTS definitions
and its associated pinmux node accordingly.

Sync the sdhci0 node from kernel. This changes the compatible that is
required to be there in the driver. Change the same for the SD card node
which is not yet supported in kernel. This also syncs the main_pmx0 node
as a side effect.
Also change the name of the driver to match the compatible in kernel.

Transition to the IOPAD macros as used in Linux in which the pin mux
mode is specified using a dedicated parameter while also dropping the
related MUX_MODEx macros that are no longer needed. This transition
will allow us to keep both Linux and U-Boot DTS in sync more easily.
While at it also align the file name of the include file itself and
update any references accordingly.

Switch from using the high priority DMSC transmit message queue used
by the secure R5 MCU island boot context to the low priority message
queue. While the change in priority is irrelevant for the current boot
architecture it however gives us access to a deeper message queue that
will allow us to buffer more messages. This is an important aspect when
sending several messages without requesting and waiting for a response
in a row which is a communication scheme used during core shutdown for
example. See AM654 TISCI User Guide for additional details.
