TCK during nSRST assert/deassert code.
To support LPRF targets (CC13xx/CC26xx), TCK must be toggled
for 50 ms while nSRST is asserted and right after it is
released. This allows the core to halt in boot ROM before
code is run that might interfere with debug access.
The current routine has two issues. It shouldn't be run at
all if the target is using SWD. And the delay needs to
be a real-time 50 ms, so the number of TCK periods should
be calculated off the set speed.

Accordingly to ARM DDI 0406C at B1.5, the security extensions for
armv7a are optional extensions and can be detected by reading
ID_PFR1.
The monitor mode is part of the security extensions and the shadow
registers "sp_mon", "lr_mon" and "spsr_mon" are only present with
the security extensions.
Read the register ID_PFR1 during cortex_a examine, determine if
security extension is present and then conditionally enable the
visibility of the monitor mode shadow registers.

"sp_mon" moved from index 37 to 39

"spsr_mon" moved from index 39 to 41

A common problem with target configurations appears to be broken
debug base address configuration. ARM DDI0406C.d specifies in App. D,
1.4.1, that bit 31 of the debug base address serves as identification
of an external debugger, as opposed to an internal access to memory
mapped debug registers by the CPU. External accesses are treated
as privileged and require no debug authentification via the lock
access register.
Sometimes the base address of a debug component is wrong even
in the targets' ROM table. In this case, the correct base address
must be specified using the -dbgbase argument when creating the
target.
This patch adds a warning when bit 31 of the debug base address
is not set, as a hint to the user.

As stated in ARM v8-A Architecture Reference Manual (ARM DDI 0487E.a)
in Chapter H4.3 DCC and ITR access modes:
Writes to EDITR trigger the instruction to be executed if the PE
is in Debug state:
- If the PE is in AArch64 state, this is an A64 instruction.
- If the PE is in AArch32 state, this is a T32 instruction
But in armv8_opcodes specifically in t32_opcodes we were using some
A32 instructions for HLT, LDRx and STRx opcodes.
Using the correct LDRx and STRx opcodes, fixes 16 and 8 bits memory access
when the PE is in AArch32 state.

Before this patch aarch64_set_breakpoint was using either A64, or A32
HLT opcode by relying on armv8_opcode helper.
This behaviors ignores the fact that in AArch32 state the core could
execute Thumb-2 instructions, and gdb could request to insert a soft
bkpt in a Thumb-2 code chunk.
In this change, we check the core_state and bkpt length to know the
correct opcode to use.
Note: based on https://sourceware.org/gdb/current/onlinedocs/gdb/ARM-Breakpoint-Kinds.html
if bkpt length/kind == 3, we should replace a 32-bit Thumb-2 opcode,
then we use twice the 16 bits Thumb-2 bkpt opcode and we fix-up the
length to 4 bytes, in order to set correctly the bpkt.
