ath10k didn't play well with other devices on a
shared irq line. This patchset fixes support for
shared legacy interrupts. 

Some rework was necessary because ath10k was using
disable_irq and CE irq masking (which is not
sufficient for shared interrupts).

Since main irq handlers are now registered after
boot, BMI is now polling for CE updates. I haven't
observed any differences in boot speed.

Also this plugs a leak I spotted during rework and
adds an option for testing different irq modes.

 * simplify ath10k_pci_irq_pending()
 * combine memory leak fix patch with a
   functionality decoupling (it's very closely
 * fix 'irq: nobody cared'
 * change MSI/MSI-X disabling parameters
 * some minor fixes & code shuffling to avoid
   forward declarations

Michal Kazior (8):
  ath10k: don't consume other's shared interrupts
  ath10k: split up pci irq code
  ath10k: don't use interrupts for BMI
  ath10k: decouple ath10k_pci_start_ce()
  ath10k: defer irq registration until hif start()
  ath10k: extract functions for legacy irq handling
  ath10k: re-add support for early fw indication
  ath10k: allow explicit MSI/MSI-X disabling
