[PATCH 2/3] KVM: arm64: Simplify visibility handling of AArch32 SPSR_*

[Marc Zyngier <maz@kernel.org>]

Since SPSR_* are not associated with any register in the sysreg array,
nor do they have .get_user()/.set_user() helpers, they are invisible to
userspace with that encoding.

Therefore hidden_user_visibility() serves no purpose here, and can be
safely removed.
