Olof Johansson 643792048e serial: sifive: enable clocks for UART when probed 
When the PWM driver was changed to disable clocks if no PWMs are enabled,
it ended up also disabling the shared parent with the UART, since the
UART doesn't do any clock enablement on its own.

To avoid these surprises, switch to clk_get_enabled().

Fixes: ace41d7564 ("pwm: sifive: Ensure the clk is enabled exactly once per running PWM")
