drm: bridge: samsung-dsim: Initialize ULPS EXIT for i.MX8M DSIM
[ Upstream commit 192948f6a923bedf461b4aa09e70a25cfb8a6041 ]
The ULPS EXIT is initialized to 0xaf in downstream BSP as well as older
revisions of this patchset, in newer revisions of the DSIM patchset it
was left out and set to 0. Fix it.
