From: Kishon Vijay Abraham I <redacted> [ Upstream commit f4455748b2126a9ba2bcc9cfb2fbcaa08de29bb2 ] No functional change. As we are intending to add additional 1-bit members in struct j721e_pcie_data/struct cdns_pcie_rc, use bitfields instead of bool since it takes less space. As discussed in [1], the preference is to use bitfileds instead of bool inside structures.
