[PATCH 04/10] media: hantro: add support for Rockchip RK3066

RK3066's VPU IP block is the predecessor from what RK3288 has.
The hardware differences are:
- supports decoding frame sizes up to 1920x1088 only
- doesn't have the 'G1_REG_SOFT_RESET' register
(requires another .reset callback for hantro_codec_ops,
since writing this register will result in non-working
IP block)
- has one ACLK/HCLK per vdpu/vepu
- ACLKs can be clocked up to 300 MHz only
- no MMU
(no changes required: CMA will be transparently used)

Add a new RK3066 variant which reflect this differences. This variant
can be used for RK3188 as well.
