soc: brcmstb: Only register SoC device on STB platforms
After moving the SoC device initialization to an early initcall in commit f780429adfbc ("soc: brcmstb: biuctrl: Move to early_initcall"), the Broadcom STB SoC device is registered on all platforms if support for the device is enabled in the kernel configuration. This causes an additional SoC device to appear on platforms that already register a native one. In case of Tegra the STB SoC device is registered as soc0 (with totally meaningless content in the sysfs attributes) and causes various scripts and programs to fail because they don't know how to parse that data. To fix this, duplicate the check from brcmstb_soc_device_early_init() that already prevents the code from doing anything nonsensical on non- STB platforms.
