Update supported read commands for EON flash parts to RD_EXTN and QUAD_IO_FAST per datasheet. Also update flash sector size to 4KiB as long as flash supports sector erase (20h) command.

No because I don't have a board running U-Boot which has an EON flash mounted. These updates are purely based on the flash datasheet.
