edi: Print debug info like others while probing for ENE chips

Instead of just "Probing for ENE KB9012 (EDI), 128 kB:", lets print
some debug info - like it is currently being printed for other chips:

Probing for ENE KB9012 (EDI), 128 kB: edi_chip_probe: hwversion 0xc3, ediid 0x04
Found ENE flash chip "KB9012 (EDI)" (128 kB, SPI) on ch341a_spi.
