[ARM] 4419/1: AT91: SAM9 USB clocks check for suspending

Browse Source 
When suspending to slow-clock mode, at91_pm_verify_clocks() is called to
ensure that all the clocks are disabled or in the correct state.

This patch replaces the "#warning TODO" messages for the SAM9 processors
with the correct code.
