[OE-core] [RFC PATCH] u-boot: remove UBOOT_MACHINE and COMPATIBLE_MACHINES

oe-core does not define any machines, so it does not make sense to
add machine specific information in the oe-core u-boot recipe and
infrastructure.
Since every machine wishing to use the u-boot recipe would need to add itself to
COMPATIBLE_MACHINES, typically via a bbappend recipe, the mechanism loses any
utility it may have had and unecessarily complicates using the u-boot recipe. By
removing it, we simplify the task of adding support for new machines.
With these two variables removed from the base recipe, UBOOT_MACHINE must now be
specified in each machine config that requires u-boot. This is already the case
for UBOOT_ENTRYPOINT and UBOOT_LOADADDRESS, so the change is minimal. For
example, a beagleboard machine config currently contains:
UBOOT_ENTRYPOINT = "0x80008000"
UBOOT_LOADADDRESS = "0x80008000"
With this change, it must now contain:
UBOOT_MACHINE = "omap3_beagle_config"
UBOOT_ENTRYPOINT = "0x80008000"
UBOOT_LOADADDRESS = "0x80008000"
