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.

-Subject: [PATCH] mtd: bcm47xxpart: fix parsing first block after aligned TRX
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-After parsing TRX we should skip to the first block placed behind it.
-Our code was working only with TRX with length not aligned to the
-blocksize. In other cases (length aligned) it was missing the block
-places right after TRX.
-
-This fixes calculation and simplifies the comment.

-Subject: [PATCH] MIPS: Only change $28 to thread_info if coming from user
- mode
-
-The SAVE_SOME macro is used to save the execution context on all
-exceptions.
-If an exception occurs while executing user code, the stack is switched
-to the kernel's stack for the current task, and register $28 is switched
-to point to the current_thread_info, which is at the bottom of the stack
-region.
-If the exception occurs while executing kernel code, the stack is left,
-and this change ensures that register $28 is not updated. This is the
-correct behaviour when the kernel can be executing on the separate irq
-stack, because the thread_info will not be at the base of it.
-
-With this change, register $28 is only switched to it's kernel
-conventional usage of the currrent thread info pointer at the point at
-which execution enters kernel space. Doing it on every exception was
-redundant, but OK without an IRQ stack, but will be erroneous once that
-is introduced.

-Subject: [PATCH] MIPS: Switch to the irq_stack in interrupts
-
-When enterring interrupt context via handle_int or except_vec_vi, switch
-to the irq_stack of the current CPU if it is not already in use.
-
-The current stack pointer is masked with the thread size and compared to
-the base or the irq stack. If it does not match then the stack pointer
-is set to the top of that stack, otherwise this is a nested irq being
-handled on the irq stack so the stack pointer should be left as it was.
-
-The in-use stack pointer is placed in the callee saved register s1. It
-will be saved to the stack when plat_irq_dispatch is invoked and can be
-restored once control returns here.

-
-Commit dda45f701c9d ("MIPS: Switch to the irq_stack in interrupts")
-changed both the normal and vectored interrupt handlers. Unfortunately
-the vectored version, "except_vec_vi_handler", was incorrectly modified
-to unconditionally jal to plat_irq_dispatch, rather than doing a jalr to
-the vectored handler that has been set up. This is ok for many platforms
-which set the vectored handler to plat_irq_dispatch anyway, but will
-cause problems with platforms that use other handlers.
