Andrzej Głąbek 2f4426663a drivers: pinctrl_nrf: Configure QSPI IO3 pin as output set high 
... so that the pin is kept in a defined state when the IO3 line is
not controlled by the QSPI peripheral (when the peripheral is disabled
or disconnected from the pin).

The IO3 pin in Quad SPI flash chips usually has dual functionality -
it is an I/O line when the chip is configured to work in Quad (4 I/O)
mode and it is a HOLD# or RESET# line when the chip is configured to
work in non-Quad (2 I/O) mode. In the latter case, it is important that
the line is kept in the inactive (high) state, otherwise communication
with the chip may be disrupted (and this actually happens when e.g.
the spi_flash sample is used on a brand new nRF5340 or nRF52840 DK -
the nrf_qspi_nor driver fails to initialize and the sample just ends
up with the "mx25r6435f@0: device not ready" message).

This commit addresses the problem in the same way that it was done for
the CSN line in commit 6d8172f4e9.
