Subject: [PATCH] power: reset: Add MFD_SYSCON depends for brcmstb

The Broadcom STB reboot driver depends on MFD_SYSCON, it uses
syscon_regmap_lookup_by_phandle() which will not lookup syscon phandles
if MFD_SYSCON is disabled, and instead will return -ENOSYS since it is
turned into an inline stub.

Sebastian,

Could you queue this as a fix for 4.1? Thanks!
