ARM: dts: at91-sama5d4_xplained: add pinctrl state dtsi file

Allow the pin controller to handle and set the state of the pins to:
* "default" on boot, resume and before performing an transfer.
* "sleep" on suspend.

This should make it possible to optimize energy usage for the pins
both for the suspend/resume cycle.

ARM: at91: add smd device definition

This patch adds SMD definition and DMA interface in device file.
The EK board contains a SmartDAA so we register the SMD interface
from that board file.

atmel_lcdfb: change pixel clock ratio calculation

DIV_ROUND_UP() was used to calculate the pixel clock divider
in atmel_hlcdfb_setup_core_base().
But this rounding was producing a bigger divider each time it was called.
We replace by DIV_ROUND_CLOSEST() to calculate it.
