ARM: i.MX: Add i.MX6sx support ...

Add some cpu type defines and clock support. The clock support
is very different from other i.MX variants, so it's a separate
file, like done in the kernel.

arm: imx6: move imx6_init_lowlevel to single initcall ...

Instead of repeating the same lowlevel init for every board
move it to it's own initcall.

Avoids code bloat and shaves off almost 1.5kB of uncompressed
barebox size for a default imx_v7_defconfig build.

For boards wherethe hostname setup was done in  the postcore
initcall we move this to a device initcall to get it out of
the way.

ARM i.MX6q: Mark VPU and IPU AXI transfers as cacheable, increase IPU priority ...

This is needed so that the IPU framebuffer scanout cannot be
starved by VPU or GPU activity.
Some boards like the SabreLite and SabreSD seem to set this in
the DCD already, but the documented register reset values do not
contain the necessary settings.

ARM: i.MX6: correct work flow of PFDs from uboot-sources ...

PFDs need to be gate/ungate after PLL lock to reset PFDs to right state.
Otherwise PFDs may lose correct state in state-machine, then no output
clock.
For i.MX6DL and i.MX6SL, ROM have taken care of PFD396 already since the
bus clock needs it.

ARM: i.MX: Add correct SoC type detection for i.MX6 ...

Using the ANATOP_SI_REV register we can only distinguish between
i.MX6q/d and i.MX6dl/s SoCs. Take the number of cores into account
to get the exact SoC type.
