[PATCH 06/10] bootargs: remove unused linux_bootargs_overwrite()

[Sascha Hauer <s.hauer@pengutronix.de>]

linux_bootargs_overwrite() lost its last user with commit fe1e02cc68cd
("bootm: add generic android image handler"), which replaced the
old ARM32 specific Android image handler calling it. Remove it together
with the linux_bootargs_overwritten state it maintained.
