This patch series reprensent a bunch of patches necessary to enable common part
of Dom0less.
The stuff necessary to start/launch domains will be introduced separately.
This patch series is based on [1], but a lot of patch could go even without
it.

Changes in v2:
- Move patch "[PATCH v1 04/27] xen/riscv: rework G-stage mode handling" to
patch series [1]
- Address the comments from ML.
- The following patches were folded into one:
# xen/riscv: implement init_intc_phandle()
# xen/riscv: call do_initcalls() in start_xen()
# xen/riscv: setup system domains
- The following patch were folded into one:
# xen/riscv: add vaplic access check
# xen/riscv: emulate guest writes to virtual APLIC MMIO
# xen/riscv: emulate guest reads from virtual APLIC MMIO
- Add new bug fix, not really necessary to this patch series:
xen/riscv: manage IRQ_DISABLED flag in APLIC irq enable/disable callbacks
