The GPIO banks are added as sub nodes or child nodes under the
pinctrl node (as per Linux ABI) and the reg property which points
to an array of controllers physical base address is removed
to align with the Linux devicetree.

This commit fixes various devicetree warnings in the at91 devicetrees
like:
arch/arm/dts/sama5d36ek_cmp.dtb: Warning (avoid_unnecessary_addr_size): /gpio_keys: unnecessary #address-cells/#size-cells without "ranges" or child "reg" property
These warnings make buildman report failed builds for most of at91 boards.
Thus, fixing it.

The device tree source files of at91sam9m10g45ek boards are copied
from the Linux v4.10, do the changes as below.
- Add the reg property for the pinctrl node.
- Move the gpio (pioA, pioB, pioC, pioD, pioE) nodes as the pinctrl's
slibling nodes, instead of the child nodes.
- Add the "u-boot,dm-pre-reloc" property to determine which nodes
are used by the board_init_f stage.
- Fix the compilation warnings.
