Similar to the riscv_is_kvm_aia_aplic_imsic() helper from riscv_aplic.c,
the existing virt_use_kvm_aia() is testing for KVM aia=aplic-imsic with
in-kernel irqchip enabled. It is not checking for a generic AIA support.

Rename the helper to virt_use_kvm_aia_aplic_imsic() to reflect what the
helper is doing, and use the existing riscv_is_kvm_aia_aplic_imsic() to
obscure details such as the presence of the in-kernel irqchip.
