Since commit 4047368938 "accel/tcg: Introduce tlb_set_page_full" we
have been seeing this assert
../accel/tcg/cputlb.c:1294: tlb_set_page_with_attrs: Assertion `is_power_of_2(size)' failed.
When running Tock on the OpenTitan machine.
The issue is that pmp_get_tlb_size() would return a TLB size that wasn't
a power of 2. The size was also smaller then TARGET_PAGE_SIZE.
This patch ensures that any TLB size less then TARGET_PAGE_SIZE is
rounded down to 1 to ensure it's a valid size.

While testing some changes to GDB's handling for the RISC-V registers
fcsr, fflags, and frm, I spotted that QEMU includes these registers
twice in the target description it sends to GDB, once in the fpu
feature, and once in the csr feature.
Right now things basically work OK, QEMU maps these registers onto two
different register numbers, e.g. fcsr maps to both 68 and 73, and GDB
can use either of these to access the register.
However, GDB's target descriptions don't really work this way, each
register should appear just once in a target description, mapping the
register name onto the number GDB should use when accessing the
register on the target. Duplicate register names actually result in
duplicate registers on the GDB side, however, as the registers have
the same name, the user can only access one of these registers.
Currently GDB has a hack in place, specifically for RISC-V, to spot
the duplicate copies of these three registers, and hide them from the
user, ensuring the user only ever sees a single copy of each.
In this commit I propose fixing this issue on the QEMU side, and in
the process, simplify the fpu register handling a little.
I think we should, remove fflags, frm, and fcsr from the two (32-bit
and 64-bit) fpu feature xml files. These files will only contain the
32 core floating point register f0 to f31. The fflags, frm, and fcsr
registers will continue to be advertised in the csr feature as they
currently are.
With that change made, I will simplify riscv_gdb_get_fpu and
riscv_gdb_set_fpu, removing the extra handling for the 3 status
registers.

The riscv target incorrectly enabled semihosting always, whether the
user asked for it or not. Call semihosting_enabled() passing the
correct value to the is_userspace argument, which fixes this and also
handles the userspace=on argument. Because we do this at translate
time, we no longer need to check the privilege level in
riscv_cpu_do_interrupt().
Note that this is a behaviour change: we used to default to
semihosting being enabled, and now the user must pass
"-semihosting-config enable=on" if they want it.

2) check whether csr is existed: raise RISCV_EXCP_ILLEGAL_INST if not
3) do access control: raise RISCV_EXCP_ILLEGAL_INST or RISCV_EXCP_VIRT_
INSTRUCTION_FAULT if not allowed
The predicates contain parts of function of both 2) and 3), So they need
