google/eve: Enable keyboard backlight in bootblock

Enable the keyboard backlight as early in boot as possible to
    provide a indication that the BIOS is executing.

Since this is bootblock it can't use the convenience function
    for checking for S3 resume so just read the PM1 value from the
    SOC and check it directly.

Use a value of 75% for the current system as that is visible
    without being full brightness.

BUG=chrome-os-partner:61464
    TEST=boot on eve and check that keyboard backlight is enabled
    as soon as the SOC starts booting
