Motion-PRO: Update EEPROM's page write bits and write delay.
Change EEPROM configuration according to the datasheet: "The 24C01A and 24C02A have a page write capability of two bytes", and "This device offers fast (1ms) byte write". Add 3ms of extra delay. Signed-off-by: Piotr Kruszynski <ppk@semihalf.com> Acked-by: Bartlomiej Sieka <tur@semihalf.com>
