Add single core R5F IPC for AM62 SoC family

AM62 SoC family don't have a multicore R5F cluster, instead they have a single core R5F.
This enables IPC support with single core R5F for AM62 family of SoCs.

While at it, also simplify the cluster mode setting usage by using soc_data specific checks only at probe.

Devarsh Thakkar (3):
remoteproc: k3-r5: Simplify cluster mode setting usage
dt-bindings: remoteproc: ti: Add new compatible for AM62 SoC family
remoteproc: k3-r5: Use separate compatible string for TI AM62x SoC

V2:
- dt-bindings: Avoid acronyms, use "Device Manager" instead of "DM"
V3:
- dt-bindings: Use separate if block for each compatible for ti,cluster-mode property
- dt-bindings: Rearrange compatibles as per alphabatical order
V4:
- dt-bindings: Place each enum in separate line in allOf
V5:
- No change (fixing typo in email address)
V6:
- dt-bindings: Remove reviewed-by due to new modifications to use cluster-mode=3
Introduce Simplify cluster-mode setting preamble patch per review
comments
- Use CLUSTER_MODE_SINGLECORE for AM62x
- Set PROC_BOOT_CFG_FLAG_R5_SINGLE_CORE for single core.
V7:
- Override to appropriate cluster-mode per firmware status flag without checking soc_data
- Set appropriate mode as default if not provided in DT
- Check mode validity against SoC data during probe
- Rebase on top of 6.3 linux-next
V8:
- Avoid using soc_data while overriding cluster mode for IPC-only mode
