With current recipe formatting CMDLINE variable contains
many unnecessary white spaces. This patch allow to drop
unnecessary spaces at the moment of writing them to
cmdline.txt. This will improve readability of cmdline.txt,
/proc/cmdline and dmesg output.

Instead of generating cmdline.txt in the kernel recipe, it is generated
in a standalone recipe and pulled in as a dependency of the bootfiles
recipe. This simplifies the process of using a linux-yocto,
linux-mainline or similiar kernel recipe instead of linux-raspberrypi.
In the rpi-cmdline recipe the command line is built from fragments which
can all be easily overridden. The variables `SERIAL` and `CMA` are
renamed to `CMDLINE_SERIAL` and `CMDLINE_CMA` for consistency. The
cmdline.txt file is created in the do_compile step to allow further
customisation via do_compile_append if needed.
