[PATCH RESEND] misc: ibmasm: fix build errors

[Randy Dunlap]

From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx>

Fix build when CONFIG_SERIAL_8250=m and CONFIG_IBM_ASM=y.

Fixes these build errors:

drivers/built-in.o: In function `ibmasm_remove_one':
module.c:(.text+0xf6874): undefined reference to `ibmasm_unregister_uart'
drivers/built-in.o: In function `ibmasm_init_one':
module.c:(.text+0xf6c37): undefined reference to `ibmasm_register_uart'
