meta-hpe: adding meta-dl385-g11 layer for HPE DL385 Gen11

altered conf-notes.txt to reflect common targets (obmc-phosphor-image)

removed IMAGE_INSTALL appends for modules. kernel-modules are an issue
anyway and recipes will be added under meta-common/recipes-phopshor/
packagegroups.

removed MACHINE_EXTRA_RDEPENDS from machine configuration file.
added under meta-comon/recipes-phopshor/packagegroups.

EXTRA_IMAGECMD:squashfs-xz: requesting to have "branch-call-jump" filter
applied to all images (bcj) with 1MB block size rather than the default
128k. (Specify for ARM architecture)

Updated machine configuration notes.

Updated Yocto target to nanbield (release 4.3) and scarthgap
future release 4.4)
