If a task registers SIGCHLD, uses waitpid(-1)
in the handler, and the task also calls waitpid,
it will fail to delete the child function

The libdsp uses M_PI_F and M_PI_2_F which are defined only in the NuttX
math library. Fix an compile error when CONFIG_LIBM is disabled and the
other math library is used.
The Atmel samv7 implements progmem functionality. However, there is
missing ARCH_HAVE_PROGMEM Kconfig symbol. This add missing symbol.

Set default console port to USART1. This allows easy access to serial
console by embedded debug CDC-ACM driver.
The README is updated with correct information about PB04 use once
samv71-xult can only be debugged using SWD mode. This means that it is
safe use CDC-ACM as default serial console.

support and Timer/counter trigger.

This commit adds DMA and TC support to SAMV7 AFEC driver. The AFEC (ADC)
can now be triggered by Timer/counter at chosen frewuency and samples can
be transfered via DMA with configurable number of samples. Timer/counter
trigger is now set as a default option with the possibility to change it
to software generated trigger.
DMA is inspired by SAMA5 driver and also uses ping pong buffers.

we have many different hostfs implementation now, so it's better
to select the implementation explicitly, just like what we have
done for arm(FS_HOSTFS vs. ARM_SEMIHOSTING_HOSTFS).

The FAT was not coherent. Resulting in a write failed
with errno:28 No space left on device.
It is unclear how the memory is acesses prior to the DMA
completion. But this restructuring ensures the data
is coherent.
This issue was not detected on the stm32h7
