kernel: bump kernel recipe

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

Cumulative changes since last bump (summarized):
 - add LTC3676 PMIC driver to allow voltage control of rails
   including VDD_ARM and VDD_SOC
 - enable LDO bypass mode

The above changes result in ARM core and IMX6 SOC voltage regulation being
moved from the internal LDO's (inefficient) to the PMIC switching regulator
(more efficient) and therefore provide the following benefits:
 - proper voltage rail settings for VDD_ARM and VDD_LDO per the IMX6 datasheet
   (without bypassing the LDO the cpufreq driver will set them to a value
    that does not account for the ~125mV drop over the LDO)
 - reducing overall CPU power draw
 - improved thermals by moving some heat from power loss from the CPU to the
   PMIC
