mb/purism/librem_cnl: Provide CBFS setting for Mini auto power on

Control Mini v1/v2 automatic power on by adding a 'board_settings' file
to CBFS.  This allows us to use one build each for Mini v1/v2 that is
configured differently for different uses.  By default, the EC setting is
not configured by coreboot, and the OS could configure it.

Add ITE SuperIO configuration to device tree and configure base address
of BRAM1.  (BRAM1 contains the EC firmware setting for automatic power
on.)

Test: Build Mini v2, boot with no settings in CBFS.  Add board_settings
configured for automatic power-on, flash, boot, confirm EC now powers
on automatically when power applied.
