Kevin Darbyshire-Bryant 088e28772c kernel: update kernel 4.4 to version 4.4.69
Refresh patches. A number of patches have landed upstream & hence are no
longer required locally:

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.
As it has now been reverted upstream it needs to be included again for
LEDE.

Run tested ar71xx Archer C7 v2 and lantiq.
