target-sparc: Split cpu_put_psr into side-effect and no-side-effect parts
For inbound migration we really want to be able to set the PSR without having any side effects, but cpu_put_psr() calls cpu_check_irqs() which might try to deliver CPU interrupts. Split cpu_put_psr() into the no-side-effect and side-effect parts. This includes reordering the cpu_check_irqs() to the end of cpu_put_psr(), because that function may actually end up calling cpu_interrupt(), which does not seem like a good thing to happen in the middle of updating the PSR.
