drm/rockchip: dw-mipi-dsi: fix possible un-balanced runtime PM enable

Browse Source 
[ Upstream commit 517f56839f581618d24f2e67a35738a5c6cbaecb ]

In the case where the bind gets deferred we would end up with a
un-balanced runtime PM enable call.

Fix this by simply moving the pm_runtime_enable call to the end of
the bind function when all paths have succeeded.
