meta-openembedded and poky: subtree updates

Squash of the following due to dependencies among them
and OpenBMC changes:

meta-openembedded: subtree update:d0748372d2..9201611135
meta-openembedded: subtree update:9201611135..17fd382f34
poky: subtree update:9052e5b32a..2e11d97b6c
poky: subtree update:2e11d97b6c..a8544811d7

The change log was too large for the jenkins plugin
to handle therefore it has been removed. Here is
the first and last commit of each subtree:

-Subject: [PATCH] Fix build breakage from lock_guard error (#6161)
-
-Summary:
-This change fixes a source issue that caused compile time error which breaks build for many fbcode services in that setup. The size() member function of channel is a const member, so member variables accessed within it are implicitly const as well. This caused error when clang fails to resolve to a constructor that takes std::mutex because the suitable constructor got rejected due to loss of constness for its argument. The fix is to add mutable modifier to the lock_ member of channel.

+Subject: [PATCH] cmake: Add check for atomic support
+
+Detect if libatomic should be linked in or compiler and platform can
+provide the needed atomic instrinsics, this helps build on certain
+platforms like mips or clang/i386
