Subject: [PATCH] ath5k: set pcie flag before calling wakeup
In ath5k_hw_nic_wakeup we do not reset the pci unit for pcie devices.
However, we didn't mark devices as pcie until after the first call to
wakeup causing such devices to hang.

Fixed whitespace and bracing issues. Also moved the comment about
getting MAC/PHY revisions back where it was originally since my moving
it didn't make any sense.
