Revert "fix[h264d_parser]: Fix pps parsing issue"

Browse source 
This reverts commit 1f8aafea1c.

Platform: General
Spec: h264

Solution:

The base line profile, Main profile, and Extended profile do not
support transform_8x8_mode_flag, pic_scaling_matrix_present_flag,
and second_chroma_qp_index_offset.

However, nonstandard sequences may incorrectly include certain
fields and some extensions or custom implementations may violate
the standard

Therefore, the processing here is strictly carried out according
to the sequence processing logic provided by the spec

Consider #516724, it has been confirmed that it is caused by
incomplete sequence reception. The revert patch here does not
affect the correctness of mpp processing

Reported-by: redmine #543598
