[v5,4/9] package/qoriq-rcw: add target rcw binary support

From: Jerry Huang <jerry.huang@nxp.com>

For NXP QorIQ (PowerPC and Layerscape) platform,
we need to specify the RCW file and build it to binary.

Introduce BR2_PACKAGE_HOST_QORIQ_RCW_BIN to specify the RCW binary file.

  It took me some time to understand: this is actually simply about an in-tree 
RCW source, rather than a custom one. So I heavily modified this patch:

      - rename the option to _RCW_INTREE;
      - update commit message, documentation, and internal variables
        accordingly;
      - reorganise condition tree so it becomes a little simpler;
      - add patsubst so the source can be specified as either %.rcw or %.bin;
      - always install it as PBL.bin, to be consistent with the custom
        option.

  Note that that last one (PBL.bin) also affects post-image scripts that use it. 
But I didn't get down to the ls1028ardb defconfig.

  Regards,
  Arnout
