Christopher Clark 028e1e0e4d machine: use weak default for kernel and KERNEL_DEVICETREE settings
To allow other layers to easily provide a default kernel preference to
use with the Raspberry Pi MACHINEs, switch to use the ??= assignment
operator for setting the default kernel and the device tree value in
this layer.

This change is motivated by enabling Xen support in meta-virtualization
to use the raspberrypi4-64 MACHINE definition from this layer with the
Yocto Linux kernels.
