majolica: Add spaces for EC firmware to enable Type-C adaptor

The next 20kByte after 128k of stock BIOS is optional to enable the
type-C DC adaptor. If you use the 148kByte, don't forget to fill the
0x20000-0x21000 which is ROMSIG to all FFs or 0s.

The old EC_majolica.bin can still be used without building error and
problems, except the type-C DC adaptor can not be used.
