enable FPU and implement up_fpucmp to pass ostest
With aggressive optimization enabled (-O2/-O3), ostest FPU test will fail.
This is because the compiler will generate additional vector
instructions between subsequent up_fpucmp() calls (loop vectorization
somewhere in usleep() call), which will consequently overwrite
the expected FPU context (XMM registers).

Add support for tricore TC397
1. Porting based on AURIX TC397 KIT_A2G_TC397_5V_TFT evaluation board
https://www.infineon.com/cms/en/product/evaluation-boards/kit_a2g_tc397_5v_tft/
2. In order to avoid license and coding style issues, The chip-level code
still uses the implementation of AURIX Development Studio SDK.
The SDK package will be downloaded as a third-party package during compilation:
https://github.com/anchao/tc397_sdk
3. Single core only, SMP implementation will be provided in the future.
4. Implemented the basic System Timer, ASCLIN UART driver.
5. Only the Tasking tool chain is supported (ctc/ltc, license maybe required)
6. 'ostest' can be completed on the TC397 development board.
How to run?
1. Setup the tasking toolchain and license
$ export TSK_LICENSE_KEY_SW160800=d22f-7473-ff5d-1b70
$ export TSK_LICENSE_SERVER=192.168.36.12:9090
2. Build nuttx ELF
$ ./tools/configure.sh tc397/nsh
$ make -j
...
artc I800: creating archive libc_fpu.a
LD: nuttx
3. Switch to windows PC, setup AURIX-studio to Debugger Launcher
4. Replace runing ELF to nuttx, and re-download ELF

I recently imported NuttX version 6.0 (and nsh) into a Microchip
Studio project [1] on Windows to figure out what was going wrong with
the avr32dev1 build. I also briefly checked NuttX version 10.
I worked with the assumption that the avr32 (avr32dev1) specific
changes to the codebase were minimal across NuttX releases.
For the initial proof of concept I used Microchip Studio version 7.0
(with the recent Microchip's ASF updates). I use avr32-gcc (4.4.7)
hosted here [2] for building NuttX for avr32dev1 on GNU/Linux.
Even with the Microchip Studio project, I had initial debug problems
with just stepping through the code a line at a time. I had to bring
in crt0, a trampoline stub and the linker file from one of my older
projects to really build on the suspicion I had with the linker file.
Perhaps an older version of avr32-gcc did something differently. I am
not sure about this. I used avr32-objdump to see the output sections
of the generated elf file. I just had to tweak the linker script to
ensure correct linking of the sections.
With those changes, I was able to inspect the UART sections within
NuttX Microchip Studio project.
Second important change: the transmit pin: I had to reassign the pin
to see the nsh console.
These are the currently assigned UART pins:
RX: PA_24 -> Physical IC pin 59
TX: PB_02 -> Physical IC pin 24
For the avr32dev1 board, they are pins: J1 (berg pin 28) and J2 (berg
pin 10).
In addition, the PR fixes silly compilation problems with avr32dev1.
I have tested the nsh build with my avr32dev1 boards. I used Atmel ICE
to program one of them (flash at 0x80000000) and dfu-programmer to
test my other board (flash at 0x80002000). The other RS-232 parameters
are the same as they were.

SAMv7 reset controller stores the cause of last reset (SW reset, power up,
pin reset etc.) in status register. This commit adds function that allows
the board to retrieve this information. This function should be called
from board support layer either during initialization or based on
incoming ioctl call.
Adding the sam_get_reset_cause() to sam_systemreset.c also resulted in
always compiling this file by default and only putting up_systemreset()
under CONFIG_SAMV7_SYSTEMRESET option.
Also header file sam_systemreset.h was created as it defines reset types
in comfortable manner for future processing in board layer. This is done
to avoid passing boardctl dependent structure to architecture layer.

Simple boot is a method of booting that doesn't depend on a 2nd
stage bootloader. Please note that some of the ESP-IDF bootloader
features are not available using simple boot, such as partition
tables and OTA: most of these features are implemented in NuttX
and MCUboot.
This commit refactors DAC driver. The functionality remains the same
but driver start up is now done in dac_setup (after application called
open function) instead of sam_dac_initialize (called from BSP). This
ensures that driver does not take resources (timer, interrupt) until
opened. Implementation of dac_shutdown is also provided, therefore
the driver frees resources once closed.
This change is consistent with other drivers implementation.
