vt6655: Fix a possible sleep-in-atomic bug in vt6655_suspend
The driver may sleep under a spinlock, and the function call path is:
vt6655_suspend (acquire the spinlock)
pci_set_power_state
__pci_start_power_transition (drivers/pci/pci.c)
msleep --> may sleep
To fix it, pci_set_power_state is called without having a spinlock.
This bug is found by my static analysis tool and my code review.
