Subject: [PATCH v7 1/2] dt-bindings: media: rockchip-vpu: Add rk3588 vpu121 compatible string

Add Hantro G1 VPU compatible string for RK3588.
RK3588 has the same Hantro G1 ip as RK3568, which are both
known as VDPU121 in TRM of RK3568 and RK3588.

Note that this VPU also has a jpeg encoder, which is one part of
the five VEPU121 jpeg encoders on RK3588. So this VPU121 shoud be
the same as vpu@...50000 on RK3399. But we don't use the compatible
string rk3399-vpu because of two reasons:
1, rk3399-vpu has disabled H264 decoding because RK3399 also has
rkvdec to support 4K H264 decoding. And we need H264 decoding because
rkvdec2 on rk3588 for H264 decoding is not supported now.
2, There are five VEPU121 jpeg encoders, but the kernel driver can't
do scheduling. So it's better to disable the VEPU121 jpeg encoder
at the moment.
