From: Wenjing Liu <wenjing.liu@xxxxxxx>
[why]
DML1 validation code doesn't have the ability to remove ODM combine.
It will directly translate currently used ODM combine config into ODM
override. If ODM combine is used in the initial state it will only
validate the timing if ODM is used. This is not correct for dynamic ODM u
se case, as ODM is used as an optimization not a hard requirement.
[how]
Remove ODM combine in the initial state before bandwidth validation so
DML will not translate it into ODM override in the initial bandwidth
validation.
