Fold the guts of kvm_arch_init() into riscv_kvm_init() instead of
bouncing through kvm_init()=>kvm_arch_init().  Functionally, this is a
glorified nop as invoking kvm_arch_init() is the very first action
performed by kvm_init().

Moving setup to riscv_kvm_init(), which is tagged __init, will allow
tagging more functions and data with __init and __ro_after_init.  And
emptying kvm_arch_init() will allow dropping the hook entirely once all
architecture implementations are nops.

No functional change intended.
