configs: apple: Enable SMBIOS / sysinfo

Enable verbose SMBIOS table generation so that user space applications
can use the SMBIOS table to provide details about the system. The
desired information is chassis-type to determine whether the system is
laptop.
Adding the chassis-type property is proposed for the upstream device
trees in the Linux kernel in [1].
Enable CMD_SMBIOS as debugging aid as the platform can easily deal with
large u-boot binaries.
