boot/xilinx-prebuilt: new boot package

This patch add a new boot package for downloading prebuilt firmware for Xilinx
versal and zynqmp evaluation boards.

It solves the problem of being able to verify the hash when downloading a
prebuilt zynqmp pmufw.elf binary.

[yann.morin.1998@free.fr:
  - move the hash file to the package dir, not the board dir
  - move board name after familly choice
  - add default board name for each family
  - qstrip the Kconfig strings before use
  - introduce XILINX_PREBUILT_BOARD_DIR to simplify paths
  - explain the *.pdi glob
  - simplify non-versal install
