Refactored MACHINE_* usage

* Added 'conf/machine/boards' as a default FILESEXTRAPATH
  (for each available layer).
* Change MACHINE_* to rely only on the path being relative to
  'conf/machine/boards'.
* Fixed up linux-xlnx.inc and linux-machine-common.inc to use 'MACHINE_*'
  for default files.
* Fixed KERNEL_DEVICETREE setting such that the variable is valid before
  the base __anonymous function of linux-dtb.inc is executed.
