Hi Stefan,

quoted

WiFi modules often require 32kHz clock to function. Add support to
enable the clock to PCIe driver.

the low power clock is independent from the host interface like PCIe. So
the clock handling should move to the common code. Sorry, not i cannot
give a good suggestion, what's the best place for this.

I think the clock is used by the PCIe device so enable it in this file. Also I checked
use of clock which in spi[0] or sdio[0] device was enabled similarly to this.
