Property hardware -- Specify that a package is tied to specific hardware.

Description
Some packages such as device drivers and HAL packages are
hardware-specific, and generally it makes no sense to add such
packages to a configuration unless the corresponding hardware is
present on your target system. Typically hardware package selection
happens automatically when you select your target. The hardware
property can be used in the body of a cdl_package command to
indicate that the package is hardware-specific.
Note: At the time of writing the hardware property is largely ignored by
the configuration tools, but this may change in future. Amongst other
possible changes, for hardware-specific packages such as device
drivers and HAL packages, the current scheme of generating a
configuration header file name based purely on the package name may be
abandoned. Instead all hardware packages would send their
configuration data to a single header file, pkgconf/hardware.h. This would make it
easier for code to obtain details of the current hardware, but
obviously there are compatibility issues. For now it is recommended
that all hardware packages specify their configuration header file
explicitly.
