Christopher Clark 1ebde9be9a xen, linux-yocto-dev, RPi4: weaker assign for KBRANCH and KMACHINE
Switch to use ?= to set KBRANCH_raspberrypi4-64 to make it easier to
override elsewhere when needed for switching to a different kernel branch.
Also make the same change for KMACHINE_raspberrypi4-64 to match how it is
assigned in the meta-yocto-bsp layer.
