Michael Brown 9b1ec3132f [realtek] Ensure EEPROM writes reach chip before starting udelay() 
On some systems, it appears to be possible for writes to the EEPROM
registers to be delayed for long enough that the EEPROM's setup and
hold times are violated, resulting in invalid data being read from the
EEPROM.

Fix by inserting a PCI read cycle immediately after writes to
RTL_9346CR, to ensure that the write has completed before starting the
udelay() used to time the SPI bus transitions.
