Move the BOARD selection out of the bootlets recipe so it can be used
from machines defined in other layers.

Move the flash parameters to the machine configuration files so it's
easier to create derivative machines and use the image bbclass to create
flash images.

The build was failing for any IMX platform because it was trying to
build a bootstream u-boot.
The u-boot variables (UBOOT_*) used by yocto were incorrectly set,
so I reworked and simplified them to fix the bug and ease maintenance.
