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

+Subject: [PATCH 09/11] MIPS: BCM63XX: add support for the on-chip EHCI
+ controller
+
+Broadcom BCM63XX SoCs include an on-chip EHCI controller which can be
+driven by the generic ehci-platform driver by using specific power
+on/off/suspend callbacks to manage clocks and hardware specific
+configuration.
