The IMX6 SoC uses an ARM Cortext-A9 which has both NEON and VFPv3 hardware
blocks. This will tune gcc to use neon instead of vfpv3 which will outperform
VFPv3.

The OpenWrt build system uses MACHINE_FEATURES of fpu to set the HAS_FPU which
in turn sets the default of CONFIG_SOFT_FLOAT as well as uClibc configuration.
As the IMX6 SoC has both vfpv3 and NEON hardware support we want to add fpu
to the feature list. This will default the IMX6 target to use -mfloat-abi=hard
which will the be most efficient use of floating point.
When switching to hard float, we also need to enable VFP support in the kernel.

Update the Ventana device-tree to match upstream:
- Add IMX6Q/IMX6DL variants for GW54xx/GW53xx/GW52xx/GW51xx
- align pinctrl with upstream
- consolidate multiple patches into one

The previous patch was not the proper fix for PCI devices that require io
resources. The new patch is the proper fix backported from mainline.

Some of the Gateworks Ventana boards have CAN bus support, therefore
we will install the userspace utils.

DMA and SDMA support are needed for ssi based audio. Note that the sdma
firmware is no longer required for ssi audio.

The interrupt mapping for legacy interrupts was backwards causing interrupts
to be mapped improperly behind a PCIe to PCI bridge (ie GW16082 mezzanine).

Enable SATA support (for IMX6D/IMX6Q) static in the kernel. It seems there
are some issues causing the driver to not load properly when built as
a module which still need to be worked out.
