nRF QSPI flash driver broken for GD25Q16

[gmarull]

Describe the bug

After pulling master I have found that the nRF QSPI flash driver is at least broken when using GD25Q16 flash found in the Adafruit feather board. I'm not sure if this affects other boards.

To Reproduce

Build the usb mass sample for adafruit_feather_nrf52840 board:

west build -b adafruit_feather_nrf52840 samples/subsys/usb/mass

Then flash using

west flash

Observe error on Zephyr console:

*** Booting Zephyr OS build zephyr-v2.4.0-89-g391935bea1c5  ***

Reverting 381cac1 seems to fix the problem.

Expected behavior

Sample works as expected, i.e. as a mass storage USB device.
