mox-support: boot.scr: fix new kernel stall when on old U-Boot

The old U-Boot (the stock one) contains old version of ARM Trusted Firmware (ATF), which has wrong initialization of USB3 PHY. This was not problem for old kernel which did not use ATF's code for phy initialization, but became a problem for new kernel.

Check whether we run with stock U-Boot, and if yes, remove USB3 PHY properties from the device tree. The old U-Boot initializes USB3 PHY on it's own.

changed milestone to %Turris OS 6.0

added Bug label

mentioned in issue turris-build#171

@kkoci shouldn't review it @prohar ? I just met that issue while using HBD for Turris MOX and if the HBD build does not work, it is not a good, because you can not recover from stalled router.

This was discussed with @mbehun and I agree on this solution. I just have to get to review this script. I already kind of did that but I am waiting for %Turris OS 5.1 going out as this affects minor versions of Turris OS. I am ok with including it to %"Turris OS 5.2" but I don't want to include non-necessary changes specially in boot process.

Didn't you need to bump PKG_VERSION?

Hmm, maybe yes. So that updater updates the script...

I think that it is not essentially required as routers affected by this issue and without this fix just won't boot and so there is not required to reinstall that package because of that.

On the other hand it makes sense to recognize the version with this fix and without it.

@jschlehofer please review bump. Bumping PKG_VERSION makes no sense as it is not used but I renamed it to PKG_RELEASE that is.

Hm, I would rather see PKG_VERSION and PKG_RELEASE together.

That is not possible as at time of fist scan it is not defined what version of kernel is going to be used I think.

I am merging this. @jschlehofer if you want to refactor these packages somehow then feel free to do so. I am not against refactor in anyway but make sure that they work as expected afterwards of course as these are essential packages for router functionality.
