[PATCH 5/5] media: hantro: Add support for the Rockchip PX30

[Paul Kocialkowski <paul.kocialkowski@bootlin.com>]

The PX30 SoC includes both the VDPU2 and VEPU2 blocks which are similar
to the RK3399 (Hantro G1/H1 with shuffled registers).

Besides taking an extra clock, it also shares an interrupt with the IOMMU
so it's necessary to request the interrupt shared.
