ipq807x: tidy up CIG WF-196 DTS file

Browse Source 
This change focuses on the I/O related cleanups for the CIG WF-196 DTS
file. Most of the removed definitions come from QCA reference files and
should have been adjusted for a custom board. List of changes:

1. Drop 'btcoex' pinctrl mux define
   WF-196 includes nRF52833 MCU which doesn't have dedicated PTA coex
   hardware interface (see [1] for software based solution in Nordic's
   nRF Connect SDK). Based on the real hardware research, defined pins
   from 'btcoex' mux aren't routed to nRF52833 MCU.

2. Drop 'spi_3' pinctrl mux define
   Defined label isn't used as reference in any other node and defined
   GPIOs most likely aren't used as well.

3. Drop GPIO 46 and 47 from hsuart pinctrl mux define
   It turned out that only UART TX and RX lines are routed between the
   main SOC (IPQ8072A) and the MCU (nRF52833).

While at it, fix also some broken indentation and redundant new lines.
