kernel: bump kernel recipe

Update to the latest gateworks_3.10.17_1.0.0_ga kernel

Cumulative changes since last bump (summarized):
 - explicitly set padctl for gpio (removes some bootloader dependence)
 - enable GW16083 Ethernet Expansion Mezzanine support
 - enable GW5520 support
 - fix EDID issues for HDMI input
 - fix for HDMI audio input sample-rates
 - disable Freescale busfreq driver by default
 - remove unused generic CPU freq scaling (imx6 has its own cpufreq handler)
