misc/eeprom: add driver for microwire 93xx46 EEPROMs

Add EEPROM driver for 93xx46 chips. It can also be used with spi_gpio driver to access 93xx46 EEPROMs connected over GPIO lines. This driver supports read/write/erase access to the EEPROM chips over sysfs files.

+	  Driver for the microwire EEPROM chipsets 93xx46x. The driver
+	  supports both read and write commands and also the command to
+	  erase the whole EEPROM.
