[PATCH openbmc v5 04/11] meta-phosphor: Make image-overlay an optional feature

[OpenBMC Patches]

From: Patrick Williams <patrick at stwcx.xyz>

Previously, obmc-bsp-common.inc added "overlay" to the IMAGE_FSTYPES
but this only has meaning if the 'image-overlay' class is used.  The
obmc-phosphor-image class explicitly includes 'image-overlay' when
appropriate but no other images (ie. ones that come with yocto) do.

Changed obmc-bsp-common to instead enable an obmc-phosphor-image feature
by setting OBMC_PHOSPHOR_IMAGE_OVERLAY=1. Then in obmc-phosphor-image we
add "overlay" to the IMAGE_FSTYPES only when the feature is enabled.

This will fix both non-phosphor images on hardware platforms and all images
on simulation platforms.
