[PATCH v6 13/17] clk: clk-bd718x7: Support BD72720 clk gate

[Matti Vaittinen <matti.vaittinen@linux.dev>]

[-- Attachment #1: Type: text/plain, Size: 2578 bytes --]

From: Matti Vaittinen <mazziesaccount@gmail.com>

The BD72720 has similar simple clk gate as a few other ROHM PMICs.

Add support for BD72720 clk gate.
