Subject: [PATCH 0/2] serial: 8250_of: support an optional bus clock

The SpacemiT UART hardware requires a bus clock to be enabled in addition
to the primary function clock.

This series makes it possible to specify both clocks via DTS.  If a
bus clock is required, it and the primary clock are fetched by name.
