Subject: [PATCH 12/63] dp-message: fix efidp_ipv4_addr fields assignment

The efidp_ipv4_addr structure has some 4-byte array fields to store IPv4
addresses and network mask. But the efidp_make_ipv4() function wrongly
casts these as a char * before dereferencing them to store a value.

Instead, cast it to a uint32_t * so the 32-bit value is correctly stored.
