Add chassis-type properties for all Apple silicon Macs. "chassis-type"
is used by u-boot to fill the SMBIOS "System Enclosure or Chassis Type"

is an laptop. The exact use case eludes me unfortunately.

The Mac Pro uses "server" as chassis-type which is not entirely
accurate. The tower and rack mount Mac Pro versions share the same .dts
file and are identical except for the enclosure. I haven't found an
obvious property in Apple's device tree to distinguish between those so
both use "server" instead of the more accurate "tower" and "rack mount
chassis". The latter chassis-types are not in dt-schema anyway.
