Sagar Shrikant Kadam 80bf6080bb tty: serial: add missing spin_lock_init for SiFive serial console
commit 17b4efdf4e4867079012a48ca10d965fe9d68822 upstream.

An uninitialised spin lock for sifive serial console raises a bad
magic spin_lock error as reported and discussed here [1].
Initialising the spin lock resolves the issue.

The fix is tested on HiFive Unleashed A00 board with Linux 5.7-rc4
and OpenSBI v0.7
