As per the HW manual, XTOSCB bit setting is as follows

If using an external clock signal, set the XTOSCB bit as 1 to
disable the crystal oscillator.

If using an external crystal, the XTOSCB bit needs to be set at 0
to enable the crystal oscillator.

Document clock and clock-names properties.

 * Added Rb tag from Geert.
v4->v5:
 * Replaced oneOf->enum for clock-names as it is simpler.
 * Added Rb tag from Conor.
v4:
 * New patch
