target-arm: make DACR banked
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.

target-arm: make TTBCR banked
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.

target-arm: make TTBR0/1 banked
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.

target-arm: respect SCR.FW, SCR.AW and SCTLR.NMFI
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.

target-arm: implement IRQ/FIQ routing to Monitor mode
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.

target-arm: move AArch32 SCR into security reglist
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.

once for secure world and once for non-secure world.

locations to specify hash bit currently set to non-secure.

target-arm: add CPREG secure state support
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.

target-arm: add async excp target_el function
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.
