1. Rename DT_COMPAT_ST_BBRAM_IT8XXX2 to COMAPT_ITE_IT8XXX2_BBRAM
2. The default configuration "$( )" should be a parentheses instead
of curly brackets. The BBRAM for it8xxx2 can be driven after
correcting.

Note that the it8xxx2 does not support a status register so that
functionality is omitted.
This change also adds driver tests that build both the npcx and it8xxx2
drivers.
