Add get_config function to I2C emulator.
Also update tests using I2C emulator to use i2c_get_config.

This driver emulates a EEPROM device in flash.
Reworked implementation with modified flash layout.
The emulation represents the EEPROM in flash as a region that is a
direct map of the eeprom data followed by a region where changes to
the eeprom data is stored. Changes are written as address-data
combinations. The size of such a combination is determined by the
flash write block size and the size of the eeprom (required address
space), with a minimum of 4 byte.
The eeprom page needs to be a multiple of the flash page. Multiple
eeprom pages is also so supported and increases the number of writes
that can be performed.
The eeprom size, pagesize and the flash partition used for the eeprom
are defined in the dts. The flash partition should allow at least two
eeprom pages. For fast read access a rambuffer can be enabled for the
eeprom (by setting the option rambuf in the dts).

Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver

At present this test uses an EEPROM emulator. Reuse the same test to
also use the real Atmel AT2x driver and an AT24 emulator, via the I2C
emulation controller.
EEPROM reads and writes for eeprom1 go through the AT2x driver, which
converts them to I2C transactions, which are passed through to the
AT24 emulator for processing. This approach makes more use of 'real'
code, in this case the Atmel AT2x driver.

Add EEPROM API test suite.
The test suite is written to run in userspace but it is currently only
whitelisted for native_posix and native_posix_64 boards which do not
support userspace.
