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

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.

These two #defines specify the offset and size of the
environment area within the total memory of your EEPROM.
- CONFIG_SYS_I2C_EEPROM_ADDR:
If defined, specified the chip address of the EEPROM device.
The default address is zero.
- CONFIG_SYS_I2C_EEPROM_BUS:
If defined, specified the i2c bus of the EEPROM device.
- CONFIG_SYS_EEPROM_PAGE_WRITE_BITS:
If defined, the number of bits used to address bytes in a
single page in the EEPROM device. A 64 byte page, for example
would require six bits.
- CONFIG_SYS_EEPROM_PAGE_WRITE_DELAY_MS:
If defined, the number of milliseconds to delay between
page writes. The default is zero milliseconds.
- CONFIG_SYS_I2C_EEPROM_ADDR_LEN:
The length in bytes of the EEPROM memory array address. Note
that this is NOT the chip address length!
- CONFIG_SYS_I2C_EEPROM_ADDR_OVERFLOW:
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.
Note that we consider the length of the address field to
still be one byte because the extra address bits are hidden
in the chip address.
- CONFIG_SYS_EEPROM_SIZE:
The size in bytes of the EEPROM device.
- CONFIG_ENV_EEPROM_IS_ON_I2C
define this, if you have I2C and SPI activated, and your
EEPROM, which holds the environment, is on the I2C bus.
