tty: serial: uartlite: Add runtime pm support

Browse source

In the commit 07e5d4ff12 ("Revert serial-uartlite: Add runtime
support") the runtime pm support was reverted to aid reverting of
the other patches.

This patch adds the runtime PM support back.
The runtime pm calls are used to gate and enable the clocks.
