85xx/kmp204x: read the IVM eeprom earlier

This allows to define the ethaddr env variable according to the the IVM content by reading the IVM in misc_init_r. Later, when HUSH is available the content read earlier is analyzed to populate some non env variables. Signed-off-by: Valentin Longchamp <valentin.longchamp@keymile.com>
