Subject: [PATCH] arm64: dts: apple: Move touchbar mipi {address,size}-cells
from dtsi to dts
Move the {address,size}-cells property from the (disabled) touchbar screen
mipi node inside the dtsi file to the model-specific dts file where it's
enabled to fix the following W=1 warnings:
t8103.dtsi:404.34-433.5: Warning (avoid_unnecessary_addr_size): /soc/dsi@...600000: unnecessary #address-cells/#size-cells without "ranges", "dma-ranges" or child "reg" property
t8112.dtsi:419.34-448.5: Warning (avoid_unnecessary_addr_size): /soc/dsi@...600000: unnecessary #address-cells/#size-cells without "ranges", "dma-ranges" or child "reg" property
Fixes: 7275e795e520 ("arm64: dts: apple: Add touchbar screen nodes")
