CRISv10: fix serial driver proc-usage
drivers/serial/crisv10.c:4428: error: unknown field 'read_proc' specified in initializer
Commit 0f043a81eb ("proc tty: remove struct
tty_operations::read_proc") removes the read_proc entry from struct
tty_operations.
Rework the proc handling in the CRISv10 serial driver to use proc_fops
instead.
