This commit adds support for TX DMA transfers for USART peripheral. Code
refactor in sam_serial.h was also required in order to have correct
defines for all possible cases (both RX and TX DMA used, just one used,
none used).

When an application is being loaded `up_addrenv_create ` calls
`create_region` to create the address environment. Only the first
entry is mapped when the region is created. Virtual memory that is
not mapped will trigger an exception when accessed. Other memory
pages are allocated and mapped on-demand. This enables setting
larger heap and stack for the process without compromising the
overall system memory.
Current `CONFIG_PAGING` refers to an experimental implementation
to enable embedded MCUs with some limited RAM space to execute
large programs from some non-random access media.
On-demand paging should be implemented for the kernel mode with
address environment implementation enabled.
Previously we need turn off the PMP locks in K230 vendor u-boot to use
NuttX, this complicates the setup process. This patch supports running
NuttX with original vendor u-boot so that to reduce setup complexity.
It also enables empty NSH prompt string in AMP master config as the apps
side support is ready.

IRQ leave with restore CURRENT_REGS
ERROR !!!
Reason:
As descript above, cpu0 swith task: thread0 -> thread1, and the
syscall() execute slowly, this time cpu1 pick thread0 to run at
up_cpu_paused(). Then cpu0 syscall execute, cpu1 IRQ leave error.
Resolve:
Move arm64_restorestate() after enter_critical_section() done

change optimization to -Os for CONFIG_DEBUG_FULLOPT to be compatible with other architectures

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).

The stack pointer must be aligned to 16 bytes, otherwise the system crash on the first unaligned data access with vector instruction.
The problem is only observable with optimization enabled, when vector instructions are generated.

During removal of F1 related stuff, code that configures FLASH
latency was removed, which rendered some of the F3 line unbootable.
It was done by mistake, since previous removed block was
'#ifdef VALUE_LINE', and block with FLASH code was '#ifndef VALUE_LINE'
and so it should not have been removed.

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
