From: Frank Chang <frank.chang@sifive.com>

The current Zjpm implementation has the following issues:

1. The address is shifted before obtaining the correct PMLEN value.
2. riscv_pm_get_pmm() does not handle effective privilege mode correctly.
3. mstatus.MPRV does not affect virtual-machine load/store instructions.
4. Sign extension for virtual-machine load/store instructions (HLV.* and
   HSV.*) must be performed when vsatp.MODE != Bare.

This patchset fixes the above issues and also renames
riscv_pm_get_virt_pmm() to riscv_pm_get_vm_ldst_pmm(), as the helper
is only used when checking the PMM configuration for virtual-machine
load/store instructions, rather than for VS/VU modes.
