[PATCH 3/4] tty: goldfish: move gf_write_ptr() to tty/goldfish.c

["Jiri Slaby (SUSE)" <jirislaby@kernel.org>]

tty/goldfish.c is the only user of gf_write_ptr(). Move it there, drop
the unneeded casts, and name it appropriately.

FTR, the last non-tty user was removed in 2018 by 4ae0fe70a097 ("Delete
the goldfish_nand driver.").
