- Avoid undefined behavior in bge_setmulti(). found by kUBSan.
- Avoid undefined behavior when setting the MAC address in bge_init().
  found by kUBSan.

 Fix a bug that SK-9D41 can't detect fiber media. Check the subsystem ID
correctly. This bug was added in if_bge.c rev. 1.161.

- Use *_FLUSH() more. The main purpose is to wait following delay() correctly.
- Add missing DELAY(80) after writing BGE_MI_MODE register.

 Modify PHY initialization code. This change fix a bug that SK-9D21 doesn't
detect MII PHY.
 - Add error check to bge_miibus_writereg().
 - Change return value of bge_miibus_readreg() when a read error occurred.
   It also add error message using with aprint_debug_dev(). This error occurs
   on some devices while detecting MII devices.
 - Move the location of BGE_MI_MODE register's initialization to next to
   bge_chipinit().
 - Set BGE_MAC_MODE before calling ifmedia_init() and/or mii_attach().
 - Add retry code for mii_attach() failed. Same as FreeBSD.
