Gabriel Somlo 1307c5d33c serial: altera_uart: fix locking in polling mode 
Since altera_uart_interrupt() may also be called from
a poll timer in "serving_softirq" context, use
spin_[lock_irqsave|unlock_irqrestore] variants, which
are appropriate for both softirq and hardware interrupt
contexts.

Fixes: 2f8b9c15cd ("altera_uart: Add support for polling mode (IRQ-less)")
