AOSCOS: staging: sb105x: replace alloc_tty_driver() with tty_alloc_driver()

Per commit 39b7b42 ("tty: stop using alloc_tty_driver"), all
instances of `alloc_tty_driver()' were revised into `tty_alloc_driver()'
with an extra `flags' argument (merged from the `flags' member of `struct
tty_driver'. The `tty_alloc_driver()' function was then removed in commit
56ec588 ("tty: drop alloc_tty_driver").

Follow this chain of changes and revise the driver code.
