drm/rockchip: vop2: set DRM_MODE_BLEND_PIXEL_NONE as alpha premutli

Browse Source 
DRM_MODE_BLEND_PIXEL_NONE usual be set at ARGB format and pixel alpha
is 0xff, no need to do blend, but vop2 platform at the following
scene, the cluster win1 and win0 do blend first, the blend result
with esmart do blend, we can't direct to close layer_mix0, because
the cluster win0 some area will do blend with esmart, so we keep
layer0 mix alpha be enabled and set as premutli mode.

zpos layer
2    cluster win1[ARGB/BLEND_COVERAGE]  -->|
1    cluster win0[ARGB/BLEND_PIXEL_NONE]-->|cluster mix-->|
0    esmart[ARGB/BLEND_PIXEL_NONE]                     -->|layer0 mix
