Russell King (Oracle) 3f9c958e35 ARM: Spectre-BHB workaround ...

commit b9baf5c8c5 upstream.

Workaround the Spectre BHB issues for Cortex-A15, Cortex-A57,
Cortex-A72, Cortex-A73 and Cortex-A75. We also include Brahma B15 as
well to be safe, which is affected by Spectre V2 in the same ways as
Cortex-A15.
