common: Add attribute to store const data in .data
On EC chips that support CONFIG_CHIP_DATA_IN_INIT_ROM, the code
execution RAM is smaller than flash, leaving some flash unused.
The CONFIG_CHIP_DATA_IN_INIT_ROM moves the .data section into the unused
flash area, where it is copied directly into data RAM at startup.
Add a new attribute __const_data that allows constant data objects to
link into the .data section instead of .rodata.
This saves 1600 bytes of RO and RW flash space on boards that enable
CONFIG_CHIP_DATA_IN_INIT_ROM.
