This change adds support for inserting virtual interrupts from HS-mode
into VS-mode using hvien and hvip csrs. This also allows for IRQ filtering
from HS-mode.
Also, the spec doesn't mandate the interrupt to be actually supported
in hardware. Which allows HS-mode to assert virtual interrupts to VS
This is to allow virtual interrupts to be inserted into S and VS
modes. Given virtual interrupts will be maintained in separate
mvip and hvip CSRs, riscv_cpu_update_mip will no longer be in the
path and interrupts need to be triggered for these cases from
rmw_hvip64 and rmw_mvip64 functions.

This series adds M and HS-mode virtual interrupt and IRQ filtering support.

With H-Ext supported, VS bits are all hardwired to one in MIDELEG

RISCV_EXCP_SEMIHOST is set to 0x10, which can be a local interrupt id
as well. This change moves RISCV_EXCP_SEMIHOST to switch case so that
async flag check is performed before invoking semihosting logic.

Apart from CLICOLOR_FORCE and GREP_OPTIONS, there are other variables

Setting the MAKE variable to a GNU Make executable does not really have

Recent dtc/libfdt can use either Make or meson as the build system.
By using a subproject, our own meson.build can remove the hard
coded list of source files.
This is also the first step towards managing downloads with .wrap
files instead of submodule.

fdt_opt == 'disabled' is going to give an error if libfdt is required
by any target, so catch that immediately. For fdt_opt == 'enabled',
instead, do not check immediately whether the internal libfdt is present.
Instead do the check after ascertaining that libfdt is absent or too old.
