The arguments/parameters of __sbi_hfence_gvma_vmid_gpa() and __sbi_hfence_vvma_asid_va() functions are swapped so we fix it. Currently, we did not face any issues because QEMU does a full TLB flush for all HFENCE instructions. We also improve documentation of HFENCE.GVMA and HFENCE.VVMA instruction encoding.
