Fix AsyncResetReg

Using SFENCE with rs1 != x0 relies on reusing the TLB hit path, but it's
not possible to hit when VM is disabled, so the logic did the wrong thing.
The simple fix is to flush the whole TLB when using SFENCE when VM is
disabled.  This shouldn't be an important performance case, because SFENCE
is nearly only used when VM is enabled (for obvious reasons).

This makes it possible to output several DTS snippets we can cat together.

This was erroneously masking id_csr_en by id_ctrl.fp; these control
signals are mutually exclusive.  Fix that, and also optimize the stall
logic to avoid stalling on unrelated CSR accesses.
