u-boot: further simplify the configuration
Remove all the bootsource selection mechanism and the horribly complicated BR2_TARGET_UBOOT_DEFAULT_ENV thing, which wanted to be generic, but was in fact very AT91-specific. Just keep things simple: we build U-Boot with the board configuration file specified in BR2_TARGET_UBOOT_BOARDNAME. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
