====================
NFC 4.4 fixes

This is the 1st NFC fixes pull request for 4.4.

It includes bug fixes and one fix for a build failure, all of them
introduced with the first NFC pull request for 4.4.

We have:

- Fix nfcmrvl SPI driver potential build error due to a broken Kconfig
  dependency.
- A few fixes for the firmware download implementation for the nfcmrvl
  UART driver.
- A GPIO allocation leak for the nfcmrvl driver.
- One code simplification for the nfcmrvl DT handling.
