Add QSPI device tree to Stratix 10.
Sync from Linux Stratix 10 dts.
Tested on Stratix 10 SoC devkit.
SOCFPGA_STRATIX10 # sf probe 0:0
SF: Detected mt25qu02g with page size 256 Bytes, erase size 64 KiB, total 256
MiB

v3->v4:
- Add qspi node to dtsi based on alphabetical order
- Add spi-tx-bus-width and spi-rx-bus-width
v2->v3:
- Change flash compatible to "jedec,spi-nor"
- Change spi-max-frequency to 100MHz
