[MIPS] Au1xx0: fix prom_getenv() to handle YAMON style environment
Alchemy boards use YAMON which passes the environment variables as the tuples of strings (the name followed by the value) unlike PMON which passes "name=<val>" strings. Signed-off-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
