Subject: [PATCH V10 2/8] arm64: dts: sc7280: Add QSPI node
From: Roja Rani Yarubandi <rojay@...eaurora.org>
Add QSPI DT node and qspi_opp_table for SC7280 SoC.
Move qspi_opp_table to / because SPI nodes assume
any child node is a spi device and so we can't put the
table underneath the spi controller.

Changes in V10:
- No changes
Changes in V9:
- No changes
Changes in V8:
- As per Doug's comments, Added "qcom,sc7280-qspi" compatible in qspi node
Changes in V6:
- As per Stephen comments, updated commit message regarding qspi_opp_table
moved from /soc to /
Changes in V4:
- As per Stephen's comment updated spi-max-frequency to 37.5MHz, moved
qspi_opp_table from /soc to / (root).
Changes in V3:
- Broken the huge V2 patch into 3 smaller patches.
1. QSPI DT nodes
2. QUP wrapper_0 DT nodes
3. QUP wrapper_1 DT nodes
Changes in V2:
- As per Doug's comments removed pinmux/pinconf subnodes.
- As per Doug's comments split of SPI, UART nodes has been done.
- Moved QSPI node before aps_smmu as per the order.
