media: platform: synopsys: VIDEO_SYNOPSYS_HDMIRX should depend on ARCH_ROCKCHIP

For now, the Synopsys HDMI HDMI RX Controller is only supported on
Rockchip RK3588 SoCs.  Hence add a dependency on ARCH_ROCKCHIP, to
prevent asking the user about this driver when configuring a kernel
without Rockchip SoC support.
