decoder: hevc: Workaround to recognize wrongly encoded main profile streams

HACK: This is a work-around to identify some main profile streams having wrong profile_idc.
There are some wrongly encoded main profile streams(eg: ENTP_C_LG_3.bin) which doesn't
have any of the profile_idc values mentioned in Annex-A, instead general_profile_idc
has been set as zero and having general_profile_compatibility_flag[general_profile_idc]
is TRUE. Assuming them as MAIN profile for now.
