discover/platform-powerpc: Return bootdev error correctlyv1.1.1
In one case get_ipmi_bootdev_ipmi() can return 0 on an error, which leads to bootdev being treated as a valid bootdev despite being uninitialised. If the planets line up correctly and bootdev is less than or equal to IPMI_BOOTDEV_SETUP, Petitboot will incorrectly apply an IPMI override. Update the error return value in get_ipmi_bootdev_ipmi(), and properly initialise bootdev. Signed-off-by: Samuel Mendoza-Jonas <sam@mendozajonas.com>
