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. Signed-off-by: Florian Fainelli <florian@openwrt.org> SVN-Revision: 39770

+Subject: [PATCH 011/174] sdhci-bcm2708: speed up DMA sync
+
+Experiments show that it doesn't really take that long to sync, so we
+can reduce the poll interval slightly. Might improve performance a bit.
