arm-trusted-firmware-mediatek: import patchset for Fidelix flash on SNFI Import pending patches to set pinconf settings for SPI-NAND pins on MT7622 identical to what the old proprietary preloader did. Should further increase the reliability of some SNFI-attached SPI-NAND flash chips.

Subject: [PATCH 3/3] mediatek: snfi: adjust drive strength to 12mA like old
loader does
In addition to FM35X1GA, also change the driver strength to 12mA for
all chips where this is done by the old/legacy U-Boot:
* Winbond 512Mb
* Winbond 1Gb
* Winbond 2Gb
* GD5F4GQ4UBYIG
* GD5F4GQ4UAYIG
* GD5F1GQ4UX
* GD5F1GQ4UE
* GD5F2GQ4UX
* GD5F2GQ4UE
