Subject: [PATCH 5.4 48/76] ARM: picoxcell: fix missing interrupt-parent properties

From: Arnd Bergmann <arnd@...db.de>

[ Upstream commit bac717171971176b78c72d15a8b6961764ab197f ]

dtc points out that the interrupts for some devices are not parsable:

picoxcell-pc3x2.dtsi:45.19-49.5: Warning (interrupts_property): /paxi/gem@...00: Missing interrupt-parent
picoxcell-pc3x2.dtsi:51.21-55.5: Warning (interrupts_property): /paxi/dmac@...00: Missing interrupt-parent
picoxcell-pc3x2.dtsi:57.21-61.5: Warning (interrupts_property): /paxi/dmac@...00: Missing interrupt-parent
picoxcell-pc3x2.dtsi:233.21-237.5: Warning (interrupts_property): /rwid-axi/axi2pico@...00000: Missing interrupt-parent

There are two VIC instances, so it's not clear which one needs to be
used. I found the BSP sources that reference VIC0, so use that:
