Subject: [PATCH] drivers/tty/nozomi.c: Use 'nozomi_setup_memory' instead of
 'setup_memory'

Several architectures (e.g. microblaze, um, and score) have already have
extern 'setup_memory', so need use 'nozomi_setup_memory' instead of, or
will cause compiling issue.

The related error (with allmodconfig for microblaze):

  CC [M]  drivers/tty/nozomi.o
drivers/tty/nozomi.c:526:13: error: conflicting types for 'setup_memory'
 static void setup_memory(struct nozomi *dc)
             ^

 void setup_memory(void);
