mtd/at25ee: Use eeprom/spi_xx25xx internally
In order to reduce code duplication, use the eeprom/spi_xx25xx driver within mtd/at25ee. The eeprom/xxx.h includes have been merged into eeprom/eeprom.h, to provide a common include file like mtd/mtd.h. Signed-off-by: Antoine Juckler <6445757+ajuckler@users.noreply.github.com>
