Marc Zyngier cbdf8a189a arm64: Force SSBS on context switch
On a CPU that doesn't support SSBS, PSTATE[12] is RES0.  In a system
where only some of the CPUs implement SSBS, we end-up losing track of
the SSBS bit across task migration.

To address this issue, let's force the SSBS bit on context switch.

Fixes: 8f04e8e6e2 ("arm64: ssbd: Add support for PSTATE.SSBS rather than trapping to EL3")
