brcm63xx: update development kernel to linux 3.14
Now that 3.13 will be EOL soon, switch to 3.14. Known issues: * 74x164 is not available because upstream dropped non-DT support * jffs2 breaks with SMP Unknown issues: * probably plenty Signed-off-by: Jonas Gorski <jogo@openwrt.org> SVN-Revision: 40380

+Subject: [PATCH 02/11] MIPS: BCM63XX: add USB device clock enable delay to
+ clock code
+
+This patch adds the required 10 micro seconds delay to the USB device
+clock enable operation. Put this where the correct clock knowledege is,
+which is in the clock code, and remove this delay from the bcm63xx_udc
+gadget driver where it was before.
