next-20210125 fails to boot on at91 sama5d2 platforms. No output is
seen, unless earlyprintk is enabled.

I have bisected this to commit e590474768f1cc04 ("driver core: Set
fw_devlink=on by default").

I've attached a log that I'm seeing on a sama5d2_xplained (sama5_defconfig
and arch/arm/boot/dts/at91-sama5d2_xplained.dts). I enabled the
following logs:
1. The ones in device_links_check_suppliers()
2. The ones in device_link_add()
3. initcall_debug=1

There seem to be some probe fails due to the pmc supplier not being ready:
calling at_xdmac_init+0x0/0x18 @ 1
platform f0010000.dma-controller: probe deferral - supplier f0014000.pmc not ready
platform f0004000.dma-controller: probe deferral - supplier f0014000.pmc not ready
initcall at_xdmac_init+0x0/0x18 returned -19 after 19531 usecs

calling udc_driver_init+0x0/0x18 @ 1
platform 300000.gadget: probe deferral - supplier f0014000.pmc not ready
initcall udc_driver_init+0x0/0x18 returned -19 after 7524 usecs

There are others too. I'm checking them.

Cheers,
