soc/intel/broadwell: Init var before use, only use when needed

root_port_init_config() pcie.c wasn't initializing a variable before
    passing its pointer to pch_iobp_exec(). pch_iobp_exec() wrote the
    uninitialized value into a register.
    In theory, the register would only be used if data was being written,
    and pch_iobp_exec()  was being used to read the data, not write it, so
    this change shouldn't have any practical effect.

Fixes coverity error:
    CID 1293134 (#1 of 1): Uninitialized scalar variable (UNINIT)
