Subject: [PATCH v2] arm64: dts: qcom: sc7280: Add wifi alias for SC7280-idp

Currently, the boot loader code used in the SC7280 SoC accesses
the WiFi node using node names (wifi@<addr>). Since the bootloader
is a common code that is used in SoCs having different WiFi chipsets,
it is better if the bootloader code accesses the WiFi node using
a WiFi alias. The advantage of this method is that the boot loader
code need not be changed for every new WiFi chip.
Therefore, add wifi alias entry for SC7280-idp device tree
