[PATCH 05/10] media: hantro: add support for Rockchip RK3036

[Alex Bee <knaerzche@gmail.com>]

RK3036's VPU IP block is the same as RK3288 has, except that it doesn't
have an encoder, decoding is supported up to 1920x1088 only and the axi
clock can be set to 300 MHz max.

Add a new RK3036 variant which reflect this differences.
