kernel: update kernel 4.4 to 4.4.69

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.

-Subject: [PATCH] x86/ioapic: Restore IO-APIC irq_chip retrigger callback
-
-commit 020eb3daaba2857b32c4cf4c82f503d6a00a67de upstream.
-
-commit d32932d02e18 removed the irq_retrigger callback from the IO-APIC
-chip and did not add it to the new IO-APIC-IR irq chip.
-
-Unfortunately the software resend fallback is not enabled on X86, so edge
-interrupts which are received during the lazy disabled state of the
-interrupt line are not retriggered and therefor lost.
-
-Restore the callbacks.
-
-[ tglx: Massaged changelog ]
-
-Fixes: d32932d02e18  ("x86/irq: Convert IOAPIC to use hierarchical irqdomain interfaces")
