ANAPARAM3 register, defined in the rtl818x common register
struct, is accessed as 16bit by rtl8187se and as 8bit by rtl8187b.
Since I have no documentation about this, I can only stick to
the reference code and to what is known to work.
This issue has been addressed by a patch from Larry Finger
that introduces an "union", in the register struct.
In my last patch-set I applied it on the register struct, but
I forget to update rtl8187 driver too.
This patch does it.

Some HP notebooks using this rtl8188ee hardware module can't get
AP scan results with pin-based interrupts mode, enabling MSI interrupts
mode could fix it.
As RealTek's testing results, RTL8188EE works well with both MSI mode
and pin-based mode fallback.

Add MSI interrupts mode support, enable it when submodules' msi_support
flag is true, also could fallback to pin-based interrupts mode if MSI
interrupts mode fails.
RealTek's policy(on modules which work well with MSI interrupts mode) is:
> If the platform supports both MSI and pin-based, use MSI.
> If the platform supports MSI only, use MSI.
> If the platform supports pin-based only, use pin-based.
Also as RealTek's testing results, RTL8188EE and RTL8723BE work well
with both MSI mode and pin-based mode fallback.

When scan request is received, scan commands are prepared and
queued into scan pending queue. There is a corner case when
command nodes are full. So we stop queueing further scan
commands and return an error. This patch makes sure that
currently queued commands in scan pending queue are also freed
in this case.

Since copy engine allocation has been revised the
ath10k_pci_ce_deinit() now simply zeroes copy
engine registers. It's probably a good idea to do
that before reseting for a more graceful device
reset.
Before ath10k_pci_ce_deinit() freed copy engine
ringbuffer memory so it was required to call it
after resetting. Otherwise it was possible for
device to access unmapped/freed copy engine
ringbuffer memory.

Definitions by which copy engine structure are
allocated do not change so it doesn't make much
sense to re-create those structures each time
device is booted (e.g. due to firmware recovery).
This should decrease chance of memory allocation
failures.
While at it remove per_transfer_context pointer
indirection. The array has been trailing the copy
engine ringbuffer structure anyway. This also
saves pointer size worth of bytes for each copy
engine ringbuffer.
