[meta-rockchip][PATCH v4 0/1] classes: rockchip-gpt-img: add

[Trevor Woerner <twoerner@gmail.com>]

Here is my v4 of this patch, based on feedback from earlier reviews.

Changes since v3:
	- I sent the wrong file when emailing v3

Changes since v2:
	- change commit message and call the "old" layout "legacy parameter"
	  format instead of "rk-boot" format
	- rename generate_rk3288_image() to generate_rk3288_loader1_image()
	- leave any older gpt image files (with datestamp) in the deploy
	  directory but just move the symlink so it always points to the most
	  recent

	- leave size variable as GPTIMG_SIZE
	- leave the boot image name as BOOT_IMG since trying to add ${MACHINE}
	  and ${DATETIME} causes the build to fail with "the basehash value
	  changed... metadata is not deterministic...". I think what was
	  wanted was that older gpt image files be left around, and this new
	  logic does that in a different way and maintains a symlink to the
	  latest

Changes since v1:
	- break large commits into smaller ones
	- rename the class and improve the commit message
