Add no-1-8-v property to sdmmc0 node to keep VDDSDMMC power rail at 3.3V.
This property will stop the LDO regulator from switching to 1.8V when the
MMC core detects an UHS SD Card. VDDSDMMC power rail is used by all the
SDMMC interface pins in GPIO mode (PA0 - PA13).

On this board, PA10 is used as GPIO to enable the power switch controlling
USB Vbus for the USB Host. The change is needed to fix the PA10 voltage
level to 3.3V instead of 1.8V.

2f9d013a0c ARM: dts: microchip: sam9x60: Add missing property atmel,usart-mode 
Add the atmel,usart-mode property to the UART nodes. This ensures
compliance with the atmel,at91-usart.yaml schema and resolves the errors
below:
serial@200: $nodename:0: 'serial@200' does not match
'^spi(@.*|-([0-9]|[1-9][0-9]+))?$'
serial@200: atmel,use-dma-rx: False schema does not allow True
serial@200: atmel,use-dma-tx: False schema does not allow True
serial@200: atmel,fifo-size: False schema does not allow [[16]]

These errors indicate that the property
atmel,usart-mode = <AT91_USART_MODE_SERIAL> is missing for
UART nodes 0, 1, 2, 3, 4, 6, 7, 8, 9, 10, 11, and 12.

d355c895fa ARM: dts: microchip: sam9x60: Fix rtc/rtt clocks 
The RTC and RTT peripherals use the timing domain slow clock (TD_SLCK),
sourced from the 32.768 kHz crystal oscillator or slow rc oscillator.

The previously used Monitoring domain slow clock (MD_SLCK) is sourced
from an internal RC oscillator which is most probably not precise enough
for real time clock purposes.

57ab1757f6 ARM: dts: microchip: sam9x60: Remove additional compatible string from GPIO node 
The driver data specific to each pinctrl GPIO bank compatible nodes are not
the same and declaring additional compatible string as fallback has no
specific purpose, hence, removing the "atmel,at91sam9x5-gpio" compatible from
sam9x60 SoC DT.

Note: The at91 pinctrl driver uses "atmel,at91rm9200-gpio" compatible string
to find the number of active GPIO banks and identify the pinmux nodes.It
should used as a constant across all DT for GPIO node banks that uses PIO3
based pinctrl driver
