drm/rockchip: vop: add rk3188 hs_start interrupt as dsp_hold

A patch from »drm/rockchip: vop: add rk3188 hs_start interrupt as dsp_hold« in state Mailinglist for linux-kernel

From: Heiko Stuebner <heiko@...> Date: Wed, 12 Sep 2018 09:50:51 +0200

Commit-Message

The hs_start interrupt on rk3188 fires at the start of a new frame, so serves essentially the same purpose as the dsp_hold_valid irq in checking when the last frame got delivered when going to standby. So define it to fix a hang on atomic_disable of the vop because the completion never really completed before.
