brcm2708: update against latest rpi-3.10.y branch

Update our copies of the brcm2708 patches to the latest rpi-3.10-y
rebased against linux-3.10.y stable (3.10.32). This should hopefully
make it easier for us in the future to leverage the raspberry/rpi-*
branches.

+Subject: [PATCH 069/174] fbdev: add FBIOCOPYAREA ioctl
+
+Based on the patch authored by Ali Gholami Rudi at
+    https://lkml.org/lkml/2009/7/13/153
+
+Provide an ioctl for userspace applications, but only if this operation
+is hardware accelerated (otherwide it does not make any sense).
