[OE-core] [PATCH] soc-family: fix SOC_FAMILY override order

[Chase Maupin]

* the current order has SOC_FAMILY settings, which are generic
  settings for a group of devices, overriding the machine specific
  settings.  For example:

  KERNEL_DEVICETREE_ti33x = "xxxx"
  KERNEL_DEVICETREE_beaglebone = "yyyy"

  Should yield "yyyy" when building for the beaglebone because
  that is a more specific device than ti33x.  However, without this
  change the result is that the value is set to "xxxx" meaning the
  more generic setting overrides the more specific setting.
