brcm2708: update linux 4.9 patches to latest version

As usual these patches were extracted and rebased from the raspberry pi repo:
https://github.com/raspberrypi/linux/tree/rpi-4.9.y

- Remove led1 from diag.sh for RPi3 since it causes boot issues.
- Fix modules.mk typos.

-Subject: [PATCH] i2c: bcm2835: Protect against unexpected TXW/RXR interrupts
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-If an unexpected TXW or RXR interrupt occurs (msg_buf_remaining == 0),
-the driver has no way to fill/drain the FIFO to stop the interrupts.
-In this case the controller has to be disabled and the transfer
-completed to avoid hang.
-
-(CLKT | ERR) and DONE interrupts are completed in their own paths, and
-the controller is disabled in the transfer function after completion.
-Unite the code paths and do disabling inside the interrupt routine.
-
-Clear interrupt status bits in the united completion path instead of
-trying to do it on every interrupt which isn't necessary.
-Only CLKT, ERR and DONE can be cleared that way.
-
-Add the status value to the error value in case of TXW/RXR errors to
-distinguish them from the other S_LEN error.
