arm64: dts: rockchip: set num-cs property for spi on px30
[ Upstream commit 334bf0710c98d391f4067b72f535d6c4c84dfb6f ]
The px30 has two spi controllers with two chip-selects each.
The num-cs property is specified as the total number of chip
selects a controllers has and is used since 2020 to find uses
of chipselects outside that range in the Rockchip spi driver.
Without the property set, the default is 1, so spi devices
using the second chipselect will not be created.
Fixes: eb1262e3cc8b ("spi: spi-rockchip: use num-cs property and ctlr->enable_gpiods")
