This means your kernel restricts accesses to /dev/mem. To overcome this, add `iomem=relaxed` to your kernel flags.
Do note that you may not be able to read the whole flash chip contents. This is because newer Intel platforms lock read and/or write access to some parts of the flash chip based on what the IFD (Intel Firmware Descriptor, also known as Intel Flash Descriptor) specifies. flashrom has a parameter to access one region at a time, however.
