sysfs IO enhancements

Add retries for some sysfs IO errors:
 EIO: Tolerate intermittant device or bus failures.
 ETIMEDOUT: Tolerate intermittant timeouts.
 EAGAIN: Tolerate drivers that do not block.
 ENXIO: Tolerate momentarily unplugged devices on busses that don't
    support hotplug.
 EBADMSG: Tolerate CRC errors.

Flush stdio buffers after writes.
Remove redundant retry and delay constants.

Resolves: openbmc/openbmc#2262
