Add disabled statuses for all devices and for those those which pins
are in conflict with other devices add a comment in the DT file to specify
this.

Overwrite sama5d2.dtsi aliases node to match the at91-sama5d27_som1_ek
board configuration. ttyS0 stands for DBGU, ttyS1 for the mikro BUS 1
serial lines and ttyS2 for the mikro BUS 2 serial lines.

the "bias-pull-up" property and set "bias-disable".

Add charger device node as a sub-device node of act8945a mfd, move
the charger's properties to this node, and use the "interrupts"
property to replace "active-semi,irq_gpios" to denote the act8945a
charger's irq.

Add pin muxing for pwm0 and set it as disabled since it is in conflict
with pins for leds.

As the board have the proper pull-ups soldered on the data and CMD
lines we don't need them specified in the PADs. So remove the
"bias-pull-up" property and set "bias-disable".
This will also save some power.

As the CAN1 interface is not multiplexed with other peripherals on this
board, enable it so that it can be tested more easily.

Add the PWM0 interface and one output of channel 0 (on PC10) on this headless
board. The output conflicts with LCD and ISI, so only enable it for this
particular board of the series (ISI is enabled on at91sam9g25ek, as an example
but we can do the other way around).

Use DMA for USART0 (which is used as ttyS1) as we have enough channels and to
show how to specify DMA use with serial nodes.
