dt-bindings: serial: 8250: support an optional second clock

Browse source

The SpacemiT UART driver requires a bus clock to be enabled in addition
to the primary function clock.  Add the option to specify two clocks
for an 8250-compatible UART, named "core" and "bus".  If both are needed,
require them to be named.
