Add interrupts property for CSI2RX. Interrupt IDs are taken from the
J721E TRM [0].

Interrupt Line      | Source Interrupt
--------------------|----------------------------
GIC500_SPI_IN_185 | CSI_RX_IF1_CSI_ERR_IRQ_0
GIC500_SPI_IN_184 | CSI_RX_IF1_CSI_IRQ_0
GIC500_SPI_IN_189 | CSI_RX_IF2_CSI_ERR_IRQ_0
GIC500_SPI_IN_188 | CSI_RX_IF2_CSI_IRQ_0
