We were missing quite a few checks for Ra or Rb required to be 31.
Further, the one place we did check we also checked for no literal
operand and the Handbook says nothing about that.

The methods by which we check for cpu features varied wildly

Replace aarch64_ldst_op_data with AArch64LdstType, as it wasn't encoded
for the proper shift for the field and was confusing.
Merge aarch64_ldst_op_data, AArch64LdstType, and a few stray opcode bits
into a single I3312_* argument, eliminating some magic numbers from the
helper functions.

This reverts commit b533f658a9.
The original code was wrong, because effectively it ignored errors
from kernel, because kernel does not return -1 on error case but
returns -errno, and does not return -EPERM for this particular ioctl.
But in some cases kernel actually returned unsuccessful result,
namely, when the dirty bitmap in requested slot does not exist
it returns -ENOENT. With new code this condition becomes an
error when it shouldn't be.
Revert that patch instead of fixing it properly this late in the
release process. I disagree with this approach, but let's make
things move _somewhere_, instead of arguing endlessly whch of
the 2 proposed fixes is better.
