soc: brcmstb: Fix error path for unsupported CPUs
[ Upstream commit 490cad5a3ad6ef0bfd3168a5063140b982f3b22a ]
In case setup_hifcpubiuctrl_regs() returns an error, because of e.g:
an unsupported CPU type, just catch that error and return instead of
blindly continuing with the initialization. This fixes a NULL pointer
de-reference with the code continuing without having a proper array of
registers to use.
