The default U-Boot environment variables and design are all set up to
have the MCU R5FSS cluster to be in Split-mode. This is the setting
in v2021.01 U-Boot and the dt nodes are synched with the kernel binding
property names in commit 468ec2f3ef ("remoteproc: k3_r5: Sync to
upstreamed kernel DT property names") merged in v2021.04-rc2.
The mode for the cluster got switched back to LockStep mode by mistake
in commit e497876343 ("arm: dts: k3-am65: Sync Linux v5.11-rc6 dts
into U-Boot") also in v2021.04-rc2. This throws the following warning
messages when early-booting the cores using default env variables,
k3_r5f_rproc r5f@41400000: Invalid op: Trying to start secondary core 2 in lockstep mode
Load Remote Processor 1 with data@addr=0x82000000 65268 bytes: Failed!
Fix this by switching back the cluster to the expected Split-mode.
Make this mode change in the u-boot specific dtsi file to avoid such
sync overrides in the future until the kernel dts is also switched to
Split-mode by default.

Add the DT nodes for the ICSSG0, ICSSG1 and ICSSG2 processor subsystems
that are present on the K3 AM65x SoCs. The three ICSSGs are identical
to each other for the most part, with the ICSSG2 supporting slightly
enhanced features for supporting SGMII PRU Ethernet. Each ICSSG instance
is represented by a PRUSS subsystem node. These nodes are enabled by
default.
DT nodes are fetch from Linux 5.13 Kernel.

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.

R5 SPL needs access to cfg space of Rings and UDMAP, therefore add RING
CFG, TCHAN CFG and RCHAN CFG address ranges.
Note that these registers are present within respective IPs but are
not populated in Linux DT nodes (as they are configured via TISCI APIs)
and hence are added to -u-boot.dtsi for now.

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

The sequence number assigned for USB subsystem in a uclass is dependent on
the order of occurrence in the device tree. If the dr_mode of USB3SS0
controller is varied then the sequence number of USB3SS1 controller also
changes. If aliases are added then sequence numbers are assigned using the
alias number. This makes the sequence number of USB3SS1 controller
independent of USB3SS0 controller's dr_mode.
Therefore, add aliases to fix the sequence number assigned to the USB
subsystems.
