The constants in enum sbi_ext_rfence_fid should match the SBI
specification. See
https://github.com/riscv/riscv-sbi-doc/blob/master/riscv-sbi.adoc#78-funct=
ion-listing

| Function Name               | FID | EID
| sbi_remote_fence_i          |   0 | 0x52464E43
| sbi_remote_sfence_vma       |   1 | 0x52464E43
| sbi_remote_sfence_vma_asid  |   2 | 0x52464E43
| sbi_remote_hfence_gvma_vmid |   3 | 0x52464E43
