tty: serial: bcm63xx: Add support for unnamed clock outputs from DT
The original non-DT bcm63xx clk code ignores the struct device argument
and looks up a global clock name. DT platforms, by contrast, often just
use a phandle to reference a clock node with no "clock-output-names"
property. Modify the UART driver to support both schemes.
