io: change inX() to have their own IO barrier overrides
Open code readX() inside inX() so that inX() variants have their own overrideable Port IO barrier combinations as __io_pbr() and __io_par() for actions to be taken before port IO and after port IO read. Signed-off-by: Sinan Kaya <okaya@codeaurora.org> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
