Add QMI client handshakes for Q6 integrated WLAN connectivity subsystem.
This module is responsible for communicating WLAN control messages to FW
over QMI interface. This patch series enables the qmi handshakes required for
WCN3990 chipset.

QUALCOMM MSM Interface(QMI) provides the control interface between
components running b/w remote processors with underlying transport layer
based on integrated chipset(shared memory) or discrete chipset(PCI/USB/SDIO/UART).

QMI client driver implementation is based on qmi framework https://lwn.net/Articles/729924/.

Below is the sequence of qmi handshake.

       QMI CLIENT(APPS)                                         QMI SERVER(FW in Q6)

                         <------wlan service discoverd----

                       -----connect to wlam qmi service----->

                       ------------wlan info request----->

                       <------------wlan info resp------------

                       ------------msa info req-------->

                     <------------msa info resp------------

                     ------------msa ready req-------->

                     <------------msa ready resp------------

                     <------------msa ready indication-------

                     ------------capability req------->

                    <------------capability resp------------

                    ------------qmi bdf req--------->

                     <------------qmi bdf resp------------

                      ------------qmi cal trigger------->

                  <------------ QMI FW ready indication-------

WLAN fw is running in modem Q6 dsp as user PD(protection domain).
Sequence of user PD loading is as following.

1) Remote proc PIL driver loads the modem fw/ROOT PD.
2) As part of ROOT pd boot-up it queries to a daemon(pd_mapper) running in apps
processor to determine how many usre pd's to be loaded by the remote processor(Q6).
3) Once user pd info is known to remote processor it loads the user pd via tftp
protocol.

Changes in V3:
	Addressed review comments from v2 version.
	Removed msa-size from dt binding and added reference to reserved-memory/reserved-memory.txt.

Changes in V2:
	Removed qmi client driver and integrated qmi client handshakes in snoc platform driver.
	Addressed comments on v1 version.
	Switched to ath10k bdf download infra(board-2.bin)
	Added MSA fixed region support to support unload use-case.
	Unified logging.

Testing:
	Tested all qmi handshakes, driver load/unload and STA/SAP sanity testing.
	Tested HW: SDM845(WCN3990)
	Tested FW: WLAN.HL.2.0-01192-QCAHLSWMTPLZ-1
