Gongqi Huang 26d6f61d49 Fix SMP compile-time error when disabling supervisor 
When generating SMP configuration with supervisor disable, the
compiler stucks at waiting for the signal from
`externalSupervisorInterrupt`, which is generated conditionally
based on `withSupervisor` option.

Joel Bodenmann ec31ed30cf Fix ambiguous function call to bind() 
The call to bind() can actually resolve to std::bind() instead of
libc's bind(). Ensure that we're definitely calling the correct one.

Leon Schuermann 9baba6d11f PmpPluginOld: fix NAPOT address calculation overflow issue 
Because pmpaddrX registers are defined to encode the address'
[XLEN + 2 downto 2] bits, the length of a NAPOT region is defined
through the most significant 0 bit in a pmpaddrX register (which in
the case of ~0 is the 33rd non-existant "virtual" bit), and the
VexRiscv PmpOld plugin represents the addresses covered by a region as
[start; end) (bounded inclusively below and exclusively above), the
start and end address registers need to be XLEN + 4 bit wide to avoid
overflows.

If such an overflow occurs, it may be that the region does not cover
any address, an issue uncovered in the Tock LiteX + VexRiscv CI during
a PMP infrastructure redesign in the Tock OS [1].

This commit has been tested on Tock's redesigned PMP infrastructure,
and by inspecting all of the intermediate signals in the PMP address
calculation through a Verilator trace file. It works correctly for
various NAPOT and TOR addresses, and I made sure that the edge cases
of pmpaddrX = [0x00000000, 0x7FFFFFFF, 0xFFFFFFFF] are all handled.
