Kconfig: Add EEPROM options to Kconfig when I2C_EEPROM is set

Browse Source 
Add the following options to drivers/misc/Kconfig:
	SYS_I2C_EEPROM_ADDR
	SYS_I2C_EEPROM_BUS
	SYS_EEPROM_SIZE
	SYS_EEPROM_PAGE_WRITE_BITS
	SYS_EEPROM_PAGE_WRITE_DELAY_MS
	SYS_I2C_EEPROM_ADDR_LEN
	SYS_I2C_EEPROM_ADDR_OVERFLOW

This does not migrate any boards, but provides a foundations for
those who want/need these options

The EEPROM page size is 2^SYS_EEPROM_PAGE_WRITE_BITS.
A 64 byte page, for example would require six bits.

Note: This is NOT the chip address length!
config SYS_I2C_EEPROM_ADDR_OVERFLOW
hex "EEPROM Address Overflow"
default 0
help
EEPROM chips that implement "address overflow" are ones
like Catalyst 24WC04/08/16 which has 9/10/11 bits of
address and the extra bits end up in the "chip address" bit
slots. This makes a 24WC08 (1Kbyte) chip look like four 256
byte chips.
