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.

As part of removing the timer_list.data field, this converts the wilc1000
driver to using from_timer and an explicit per-timer data field, since
there doesn't appear to be a way to sanely resolve vif from hif_drv.
