Atmel SoCs and the newly added CONFIG_DELAY_DEVICE_PROBES option

[Sylvain Rochet]

Hi,

FYI, to save you a git bisect, the recently added 
CONFIG_DELAY_DEVICE_PROBES (enabled by default) breaks Atmel SoCs.

For a few of quickly noticeable issues:
- PM is not working:   at91_pm_sram_init: sram pool unavailable!
- Watchdog is not even probed
- on -ek boards the wm8904 is not probed either.

Disabling CONFIG_DELAY_DEVICE_PROBES fixes all issues.

Tomeu, what should I provide to help find out what's happening ?
