Subject: [PATCH V7 1/7] 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.
