brcm2708: update linux 4.4 patches to latest version

As usual these patches were extracted and rebased from the raspberry pi repo:
https://github.com/raspberrypi/linux/tree/rpi-4.4.y

- led1 can't be controlled on rpi-3 for linux 4.4, remove it.
- Fix modules.mk typos.

+Subject: [PATCH] BCM270X_DT: Update UART0 clock-frequency
+
+The Raspberry Pi firmware now sets the UART0 clock frequency to
+48MHz (was 3MHz), to allow for baudrates up to 3MHz. This value
+is overwritten by the firmware, but alternative loaders such
+as U-Boot ignore the firmware-provided DTB. And besides, the
+default ought to be correct.
+
