> These are all "early clocks" that require initialization just at
> of_clk_init() time. Use CLK_OF_DECLARE() to declare them.
> This also fixes a problem that was spotted when fw_devlink was
> set to 'on' by default: the boards failed to boot. The reason is
> that CLK_OF_DECLARE_DRIVER() clears the OF_POPULATED and causes
> the consumers of the clock to be postponed by fw_devlink until
> the second initialization routine of the clock has been completed.
> One of the consumers of the clock is the timer, which is used as a
> clocksource, and needs the clock initialized early. Postponing the
> timers caused the fail at boot.
