Merge of the v8_el2_cp_reginfo and el3_cp_reginfo ARMCPRegInfo lists.
Previously, some EL3 registers were restricted to the ARMv8 list under the
impression that they were not needed on ARMv7. However, this is not the case
as the ARMv7/32-bit variants rely on the ARMv8/64-bit variants to handle
migration and reset. For this reason they must always exist.

When EL3 is running in AArch32 (or ARMv7 with Security Extensions)
DACR has a secure and a non-secure instance. Adds definition for DACR32_EL2.
Backports commit 0c17d68c1d3d6c35f37f5692042d2edb65c8bcc0 from qemu
Adds secure and non-secure bank register suport for TTBCR.
Added new struct to compartmentalize the TCR data and masks. Removed old
tcr/ttbcr data and added a 4 element array of the new structs in cp15. This
allows for one entry per EL. Added a CP register definition for TCR_EL3.
Backports commit 11f136ee25232a00f433cefe98ee33cd614ecccc from qemu
Adds secure and non-secure bank register suport for TTBR0 and TTBR1.
Changes include adding secure and non-secure instances of ttbr0 and ttbr1 as
well as a CP register definition for TTBR0_EL3. Added a union containing
both EL based array fields and secure and non-secure fields mapped to them.
Updated accesses to use A32_BANKED_CURRENT_REG_GET macro.
Backports commit 7dd8c9af0d9d18fb3e54a4843b3bb1398bd330bc to qemu
Add checks of SCR AW/FW bits when performing writes of CPSR. These SCR bits
are used to control whether the CPSR masking bits can be adjusted from
non-secure state.
Backports commit 6e8801f9dea9e10449f4fd7d85dbe8cab708a686 from qemu
Use MVBAR register as exception vector base address for
exceptions taken to CPU monitor mode.
Backports commit e89e51a17ea0d8aef9bf9b766c98f963e835fbf2 from qemu
Added CP register defintions for SDER and SDER32_EL3 as well as cp15.sder for
register storage.
Backports commit 144634ae6c1618dcee6aced9c0d4427844154091 from qemu
Implements NSACR register with corresponding read/write functions
for ARMv7 and ARMv8.
Backports commit 770225764f831031d2e1453f69c365eb1b647d87 from qemu
SCR.{IRQ/FIQ} bits allow to route IRQ/FIQ exceptions to monitor CPU
mode. When taking IRQ exception to monitor mode FIQ exception is
additionally masked.
Backports commit de38d23b542efca54108ef28bcc0efe96f378d2e from qemu
Define a new ARM CP register info list for the ARMv7 Security Extension
feature. Register that list only for ARM cores with Security Extension/EL3
support. Moving AArch32 SCR into Security Extension register group.
Backports commit 0f1a3b2470d798ad5335eb9d6236f02ff64e31a8 from qemu
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.
