drm/msm/dp: fix bridge lifetime

In the Linux kernel, the following vulnerability has been resolved:

drm/msm/dp: fix bridge lifetime

Device-managed resources allocated post component bind must be tied to

the lifetime of the aggregate DRM device or they will not necessarily be

released when binding of the aggregate device is deferred.

This can lead resource leaks or failure to bind the aggregate device

when binding is later retried and a second attempt to allocate the

resources is made.

For the DP bridges, previously allocated bridges will leak on probe

deferral.

Fix this by amending the DP parser interface and tying the lifetime of

the bridge device to the DRM device rather than DP platform device.
