[PATCH v3 2/6] DynamicTablesPkg: DynamicPlatRepoLib: Fix incorrect dereferencing

["Kun Qin" <kuqin12@gmail.com>]

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3996

The content of token should be derived from the data section of the
`CmObject` instead of the object itself.

This change fixed the issue by dereferencing the token value from the
data buffer of input CmObject.
