ARM: dts: AM33xx: Correct gpio #interrupt-cells property

Following commit ff5c9059 and therefore other omap platforms using
the gpio-omap driver correct the #interrupt-cells property on am33xx
too. The omap gpio binding documentaion also states that
the #interrupt-cells property should be 2.

This matches the vendor 3.8.x configuration that is shipping

The LED layout is now:
 USR0: heartbeat
 USR1: mmc0 (micro-SD slot)
 USR2: cpu0
 USR3: mmc1 (eMMC)

The cpu0 triggers was put in between the mmc triggers to make
is easier to see where the disk activity is.

ARM: dts: AM33XX: use pinmux node defined in included file

am33xx boards DTS include the am33xx.dtsi Device Tree
source file that already define a pinmux device node for
the AM33XX SoC Pin Multiplex.

Redefining this for each board makes the Device Tree files
harder to modify and maintain so let's just use what is
already defined in the included .dtsi file.

ARM: dts: AM33XX: don't redefine OCP bus and device nodes

The On Chip Peripherals (OCP) device node is a simplified
representation of the AM33XX SoC interconnect. An OCP dev
node is already defined in the am33xx.dtsi Device Tree
source file included by am33xx based boards so there is
no need to redefine this on each board DT file.

Also, the OCP and IP modules directly connected to it are SoC
internal details that is better to keep outside of board files.

sound: soc: soc-dmaengine-pcm: Add support for new DMAEngine request API

Formerly these resources were coming HWMOD on OMAP-like SoCs. With the
impending removal of HWMOD data, drivers are being converted to use the
"of-dma" method of requesting DMA channels which from DT and can be obtained
using the dma_request_slave_channel API. Add support to the soc-dmaengine-pcm
helpers so that we can fetch and open channels using this method.
