drivers: ele: remove sab_init() initialization

ELE firmware has been divided into 2 firmwares for i.MX8ULP and i.MX95:
Primary and secondary firmware.
SAB init command is in Secondary firmware, which will be loaded when
rootfs comes up, so this command is not available when OP-TEE is
initializing.
Moreover, we are not using any ELE command which is available in
secondary firmware, So removing sab_init() function.
Will add it when it will be used in driver.
