ARM: 9196/1: spectre-bhb: enable for Cortex-A15

Browse Source 
[ Upstream commit 0dc14aa94ccd8ba35eb17a0f9b123d1566efd39e ]

The Spectre-BHB mitigations were inadvertently left disabled for
Cortex-A15, due to the fact that cpu_v7_bugs_init() is not called in
that case. So fix that.

Fixes: b9baf5c8c5c3 ("ARM: Spectre-BHB workaround")
