They're provided as callbacks in ath10k_hif_ops and should be accessed
that way, if needed outside of snoc.c, and anyway, they're currently
unused outside snoc.c.

ath10k_wcn3990_clk_info and ath10k_wcn3990_vreg_info are not
WCN3990-specific structures. They hold generic data. So don't name them
with wcn3990 specifics.

Whenever the WCN3990 firmware becomes unavailable,
the host driver receives a FW down indication, post
which all the direct hardware register access should
be avoided, in order to prevent improper behavior in
the host driver.
Set the crash_flush flag when the host driver receives
a FW_DOWN_IND via qmi, in order to stop the untimely
hardware register access. Also handle the case, where
we need to do core register only for the first FW_READY
indication, which is when we initialize the host driver.
All the subsequent FW_READY indication will be received
in subsystem recovery case and we only need to do the
restart work. The state of driver is maintained using
flags to distinguish between first and subsequent FW_READY
indication received.

Add WCN3990 QMI client handshakes for Q6 integrated WLAN connectivity
subsystem. This layer is responsible for communicating qmi control
messages to wifi fw QMI service using QMI messaging protocol.
Qualcomm MSM Interface(QMI) is a messaging format used to communicate
between components running between remote processors with underlying
transport layer based on integrated chipset(shared memory) or
discrete chipset(PCI/USB/SDIO/UART).

It's easier to violate abstractions and introduce bugs when snoc.h is
including pci.h. Let's not do that.
I'm not extremely familiar with this driver yet, but several of the
shared PCI/SNOC bits seem to be related to the Copy Engine, so move them
to ce.h.

WCN3990 is integrated 802.11ac chipset with SNOC
bus interface. Add snoc layer driver registration
and associated ops.
WCN3990 support is not yet complete as cold-boot
handshake is done using qmi(Qualcomm-MSM-Interface)
and qmi client support will be added once qmi framework
is available.
