Bump the 17.01 tree kernel to 4.4.69. Trunk 4.4 and 17.01 4.4 have diverged, talked this
through with jow, he was okay with a clean diff against 17.01 and not a backported trunk
patch.

The following patches were applied upstream:

* 062-[1-6]-MIPS-* series
* 042-0004-mtd-bcm47xxpart-fix-parsing-first-block

Reintroduced lantiq/patches-4.4/0050-MIPS-Lantiq-Fix-cascaded-IRQ-setup, as
it was incorrectly included upstream thus dropped from LEDE, but subsequently
reverted upstream. Thanks to Kevin Darbyshire-Bryant for pointing me to it.

  Compile-tested on: ar71xx, ramips/mt7621, x86/64.

  Run-tested on: ar71xx, ramips/mt7621, x86/64.

Build profile for Asmax AR 1004g refers to an invalid DTS "rg100a". The
correct DTS for this device is "ar1004g".

Add support for the Observa Telecom VH4032N router.

This is another BCM6368 router, 128 MB RAM, 32MB flash and 3 USB
host ports.

The wifi chip is an onboard Broadcom BCM43222.

Probe the switch through DT instead of a platform device. This fixes
probe, as GPIO offsets are now properly accounted for.

Fixes the following issue:

[    0.802953] 8021q: 802.1Q VLAN Support v1.8
[    0.810518] rtl8366_smi: gpio_request failed for 18, err=-517

BCM6362 and BCM3380 seem to share the same PRID. Disable serial output
for them until we can find a way to tell them apart reliably.

Make sure we do a proper reset of the phy, if the phy reset is defined.

Setting the clear bit for an interrupt seems to cause interrupts to be
deasserted again immediately. So unset the bit for BCM6318 to allow
subsequent interrupts to still work.

Prevents crashes when IRQs arrive when the current kernel stack context
already contains deeply nested function calls, e.g. when stacking lots
of network devices on top of each other
