Prepare for cp register banking by inserting every cp register twice,
once for secure world and once for non-secure world.
Backports commit 3f3c82a57d128aa3ec823aa8032867c3a6e2e795 from qemu
Added additional NS-bit to CPREG hash encoding. Updated hash lookup
locations to specify hash bit currently set to non-secure.
Backports commit 51a79b039728277e35fd19f7a7b4bc6cb323697f from qemu
Prepare ARMCPRegInfo to support specifying two fieldoffsets per
register definition. This will allow us to keep one register
definition for banked registers (different offsets for secure/
non-secure world).
Also added secure state tracking field and flags. This allows for
identification of the register info secure state.
Backports commit c3e302606253a17568dc3ef30238f102468f7ee1 from qemu
Adds a dedicated function and a lookup table for determining the target
exception level of IRQ and FIQ exceptions. The lookup table is taken from the
ARMv7 and ARMv8 specification exception routing tables.
Backports commit 0eeb17d618361a0f4faddc160e33598b23da6dd5 from qemu
The extra information is not yet used but it is now available.
This requires minor changes through all of the tcg backends.
