[yocto] [meta-raspberrypi][PATCH 1/1] layer.conf: set layer depends

[Petter Mabäcker]

Ensure that build fails in a informative way if not all layer
requirements are fulfilled.

To disable strict layer depend set 'LAYERDEPENDS_raspberrypi = ""'
in local.conf.

Also set a high layer prio to ensure that meta-raspberrypi addons
are always prioritized above the depended layers.

[Feature #46]
