For most nodes with a compatible property a platform device is created.
For some an amba device is created instead. For the latter
of_amba_device_create() emits a message at debug level about the node
the device is created from. Add a similar message to
of_platform_device_create_pdata() to inform about the whole list of
created devices.

This also gives the right context for the following messages that
inform about created child devices.

power-domain from being required for that platform to fix the warning

All the RZ/G2L and alike SoC's (listed below) have ECCRAM0/1 interrupts
supported by the IRQC block, reflect the same in DT binding doc.

- R9A07G043U              - RZ/G2UL
- R9A07G044L/R9A07G044LC  - RZ/{G2L,G2LC}
- R9A07G054               - RZ/V2L
- R9A08G045               - RZ/G3S

For the RZ/G3S SoC ("R9A08G045") ECCRAM0/1 interrupts combined into single
interrupt so we just use the below to represent them:
- ec7tie1-0
- ec7tie2-0
- ec7tiovf-0

Previously, it was assumed that BUS-error and ECCRAM0/1 error interrupts
were only supported by RZ/G2UL ("R9A07G043U") and RZ/G3S ("R9A08G045")
SoCs. However, in reality, all RZ/G2L and similar SoCs (listed above)
support these interrupts. Therefore, mark the 'interrupt-names' property
as required for all the SoCs and update the example node in the binding
document.

Change in clocks is due to IP is itself configurable and

There are some differences compare to txt version.
1. DT overlay can't be described in example that's why directly include
information from overlay to node which was referenced. It is visible in
example with /* DT Overlay contains: &... */

2. All example have been rewritten to be simpler and describe only full
reconfiguration and partial reconfiguration with one bridge.
Completely drop the case where fpga region can inside partial
reconfiguration region which is already described in description

3. Fixed some typos in descriptions compare to txt version but most of it
