Ryo Takakura e1ca3ff28a serial: sifive: lock port in startup()/shutdown() callbacks 
startup()/shutdown() callbacks access SIFIVE_SERIAL_IE_OFFS.
The register is also accessed from write() callback.

If console were printing and startup()/shutdown() callback
gets called, its access to the register could be overwritten.

Add port->lock to startup()/shutdown() callbacks to make sure
their access to SIFIVE_SERIAL_IE_OFFS is synchronized against
write() callback.

Fixes: 45c054d081 ("tty: serial: add driver for the SiFive UART")
