There is only one debug unit in the sam9x60 SOC and it has the chipid
register. So defining these dbgu compatible strings to the flexcom usart
is not correct and causes the SOC detection failure. So removing these
dbgu compatible strings defined under the flexcom usart and updating
the yaml file accordingly.
---
v2 changes:
1. Updating the dt-bindings documentation and send one more patch for
the yaml file.
---
v3 change:
1. Explained the issue in the commit message rather than in the cover
letter. Added the detailed commit message for the changes done.

There is only one debug unit in the sam9x60 SOC and it has the chipid
register. So, the dbgu compatible strings are valid only for debug usart.
Defining these dbgu compatible strings are not valid for flexcom usart.
So adding the items which is valid only for flexcom usart and removing
the microchip,sam9x60-usart compatible string from the enum list as no
usart node defines only this specific compatible string.

Defining the dbgu compatible strings in the UART submodule of the
flexcom gives the below error log,
AT91: Could not find matching SoC description
This error arises due to defining the dbgu compatible strings to
the flexcom usart which is not valid because there is only one debug unit
in the sam9x60 SOC and it has the chipid register. The dbgu compatible
strings are valid only for debug usart and not valid for flexcom usart.
Thus removing the dbgu compatible strings in the UART submodule of the
flexcom for the proper SOC detection.
Fixes: 99c808335877 (ARM: dts: at91: sam9x60: Add missing flexcom definitions)

Acked-by: Alexander Dahl <ada@thorsis.com>
(The diff of the patch is identical to the diff of a quick hacked
patch I made weeks ago for my BSP which fixed the issue. SoC variant
was reported correctly on serial console on boot again. However I did
not actually test *your* patch on my hardware (sam9x60 curiosity),
thus Acked-by and not Tested-by.)
