From: Leo Li <sunpeng.li at amd.com>

[Why]

There are currently known backlight and abm issues when IPS is enabled
on DCN35.

While the issues are being ironed out, let's default to
IPS_DISABLE_DYNAMIC so users will not experience hangs. When the issues
are resolved, this patch should be reverted.

[How]

Set the default IPS config to DMUB_IPS_DISABLE_DYNAMIC
