[PATCH v3 08/10] clk: bd718x7: Support ROHM BD73800

[Matti Vaittinen]

From: Matti Vaittinen <mazziesaccount@xxxxxxxxx>

The ROHM BD73800 PMIC has a 32.768 kHz clock gate. Add support for
controlling this clock.

NOTE: The CLKOUT pin can be muxed by an OTP option. On some OTP
configurations the CLKOUT is not outputting the clk signal.
