Sync j7200 dts with Linux 6.6-rc1
- k3-j7200-r5-common-proc-board.dts now inherits from
k3-j7200-common-proc-board.dts instead of k3-j7200-som-p0.dtsi. This
allows us to trim down the r5 file considerably by using existing
properties
- remove pimux nodes from r5 file
- remove duplicate nodes & node properties from r5/u-boot files
- mcu_timer0 now used instead of timer1
mcu_timer0 device id added to dev-data.c file in order to work
- remove cpsw node
This node is no longer required since the compatible is now fixed
- remove dummy_clock_19_2_mhz
This node wasn't being used anyhere, so it was removed
- remove dummy_clock_200mhz
main_sdhci0 & main_sdhci1 no longer need dummy clock for eMMC/SD
- fix secure proxy node
mcu_secproxy changed to used secure_prxy_mcu which is already
defined in k3-j7200-mcu-wakeup.dtsi
- removed &mcu_ringacc property override since they're present in
v6.6-rc1

This resyncs the dts files for all of the currently in-tree K3
platforms, along with relevant bindings, with the v5.14 Linux Kernel
release. Of note are that the main-navss/mcu-navss nodes were renamed
to main_navss / mcu_navss and so the u-boot.dtsi files needed to be
updated to match.
Tested on j721e_evm and am65x_evm.

Sync all J7200 related v5.11-rc6 Linux kernel dts into U-Boot.
MCU R5F nodes are not yet added in Linux kernel yet but were added
in U-Boot. In order to avoid regressions, r5f nodes are kept intact.
These will be added in kernel in future.

The K3 R5F remoteproc driver in U-Boot was upstreamed prior to the
equivalent remoteproc driver in the Linux kernel. Some of the DT
properties used in U-Boot got upstreamed using different names
in Linux kernel.
The modified property names include the R5F cluster mode configuration
property "lockstep-mode"; and three different individual R5F core config
properties - "atcm-enable", "btcm-enable" and "loczrama". The property
names were updated as follows:
lockstep-mode => ti,cluster-mode
atcm-enable => ti,atcm-enable
btcm-enable => ti,btcm-enable
loczrama => ti,loczrama
Update the K3 R5F remoteproc driver, the corresponding binding, and
all the existing usage in AM65x, J721E and J7200 dts files all at
once to use the new properties and to not break any bisectability.

The J7200 SoCs have 2 dual-core Arm Cortex-R5F processor (R5FSS)
subsystems/clusters. One R5F cluster is present within the MCU
domain (MCU_R5FSS0), and the other one is present within the MAIN
domain (MAIN_R5FSS0). Each of these can be configured at boot time
to be either run in a LockStep mode or in an Asymmetric Multi
Processing (AMP) fashion in Split-mode. These subsystems have 64 KB
each Tightly-Coupled Memory (TCM) internal memories for each core
split between two banks - ATCM and BTCM (further interleaved into
two banks). The TCMs of both Cores are combined in LockStep-mode
to provide a larger 128 KB of memory.
Add the DT node for the MCU domain R5F cluster/subsystem, the two
R5F cores are added as child nodes to the main cluster/subsystem node.
The cluster is configured to run in LockStep mode by default, with
the ATCMs enabled to allow the R5 cores to execute code from DDR with
boot-strapping code from ATCM. The inter-processor communication
between the main A72 cores and these processors is achieved through
shared memory and Mailboxes.
