31b916c485 MPFS: Add kernel space mappings 
Mappings are done with vaddr=paddr.
- I/O space mapped with two gigapages
- Kernel space mapped to statically allocated page tables. 2MB of kernel
  memory is supported.
- Page pool is mapped to the kernel space, to allow virtual memory access
  for the kernel e.g. to initialize the page memory when it is allocated.

b3baf95835 UMM: Implement getter for address environment heap start vaddr 
Using the Kconfig macro does not work for RISC-V target, as there the
user heap follows .data/.bss and does not obey any Kconfig provided
boundary.

Added stubs for ARM and Z80 also.

3d8ba496a2 RISC-V: Add pgpool to vaddr utility function 
The only mapping that is supported now is vaddr=paddr, but the function
DOES check that the address is within the page pool, so it is not
useless.

1322f82802 RISC-V: Copy kernel memory mappings to userspace addrenv 
Copy the kernel mappings to the new (user) address environment. The
copyuing is done exactly once. This relies on the fact that the kernel
L1/L2 mappings will never change, as all of the kernel memory is mapped
upon boot.

57127b9429 RISC-V: Initial support for CONFIG_BUILD_KERNEL 
This implements initial support for kernel build (address environments,
page allocator) for RISC-V.

This is done a bit differently compared to the ARMV7 implementation:

- Support implemented for Sv39 MMU, however the implementation should be
  extensible for other MMU types also.
- Instead of preserving and moving the L1 references around, a canonical
  approach is used instead, where the page table base address register
  is switched upon context switch.
- To preserve a bit of memory, only a single L1/L2 table is supported,
  this gives access to 1GiB of virtual memory for each process, which
  should be more than enough.

Some things worth noting:
- Assumes page pool is mapped with vaddr=paddr mappings
- The CONFIG_ARCH_XXXX_VBASE and CONFIG_ARCH_XXXX_NPAGES values are
  ignored, with the exception of CONFIG_ARCH_DATA_VBASE which is used
  for ARCH_DATA_RESERVE
- ARCH_DATA_RESERVE is placed at the beginning of the userspace task's
  address environment

04f81ecddb arch: risc-v: Do not enable FPU for K210 with QEMU 
Summary:
- I noticed that maix-bit:smp does not work with QEMU.
- Actually, QEMU supports sifive_u (not K210) but it works
  if FPU is disabled.
- This commit fixes this issue.

Impact:
- K210 with QEMU only

Testing:
- Tested with qemu-5.2
