[OE-core] [PATCH] Add KERNEL_EXTRA_ARGS parameter

With recent kernel versions, some ARM configurations need may fail to
build with errors like this:
multiple load addresses: 0x80008000 0x80008000
This is incompatible with uImages
Specify LOADADDR on the commandline to build an uImage
We cannot pass this information in EXTRA_OEMAKE, as
"meta/classes/kernel.bbclass" explicitly ignores all EXTRA_OEMAKE
settings. So add KERNEL_EXTRA_ARGS parameter so affected boards
can add for example
KERNEL_EXTRA_ARGS = "LOADADDR=0x80008000"
to their configuration. We make this general enough so other needed
command line options can be passed as well when compiling the kernel.
