parisc architecture late bug fixes for kernel v5.16

- Fix a bug in the C code which calculates the relevant futex spinlock based on
the futex virtual address. In some cases a wrong spinlock (compared to what
is calculated in the assembly code path) was choosen which then can lead to
deadlocks.

- The 64-bit kernel missed to clip the LWS number in the Light-weight-syscall
path for 32-bit processes.

- Prevent CPU register dump to show stale value in IIR register on access rights traps.

- Remove unused ARCH_DEFCONFIG entries.
