[PATCH 1/2] ARM: dts: at91: sama7g5: Add QSPI nodes

From: Tudor Ambarus <hidden>
Date: 2021-12-09 12:36:49 

sama7g5 embedds 2 instances of QSPI controller:
1/ OSPI0 Supporting Up to 200 MHz DDR. Octal, TwinQuad, Hyperflash
   and OctaFlash Protocols Supported.
2/ QSPI1 Supporting Up to 90 MHz DDR/133 MHz SDR.
