Thanks for the suggestion Michael. We have removed all duplicates of "opensslconf.h" from our code stack. With those changes, we see all errors related to "DEPRECATEDIN_1_1_0" are gone. Now, we are not seeing any errors pointing to "bio.h". However, we have some other errors, where it points to "x509.h and x509_vfy.h". Following are a few of the errors, I am seeing:

Error in "opensslconf.h" points to 'extern "C"' statement the following code:
#ifdef __cplusplus
extern "C" {
#endif
extern "C" {
#endif
Can you please suggest us to remove these errors.
Appreciate your help on this.

You seem to be failing to include the opensslconf.h that was created as part of the build process (before including bio.h, etc). opensslconf.h is included by many of the OpenSSL headers, but not bio.h.
So either you need an explicit #include <openssl/opensslconf.h> before including any other OpenSSL headers; or you have one, but you're picking up the wrong opensslconf.h. (The latter is an easy mistake to make, as not everyone realizes opensslconf.h is a generated file and applications must include the one corresponding to the precise build they're using.)
