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.
