The POSIX standard dictates that during abnormal termination the functions
registered by atexit() are _not_ called, also flushing the streams is
optional. So in this case, it is perfectly legal / better to call the
kernel system call _exit() instead.
This fixes regression issues caused by removal exit() from the kernel.

This reverts commit 62c15c03d3.
Fix warning: the choice symbol STM32_FLASH_CONFIG_G (defined at arch/arm/src/stm32/Kconfig:1275) is selected by the following symbols, but select/imply has no effect on choice symbols
- ARCH_CHIP_STM32F412ZG (defined at arch/arm/src/stm32/Kconfig:1014)
The original code hard-coded card detection to the low when card is
inserted and high when not. This might not be true on every board
because it depends on the slot and wiring used. The second reason is
because it is also possible to detect card with D3 pin pull-up when the
slot does not provide dedicated card detection switch.
This introduces new argument to the sam_hsmci_initialize to allow
invert of card detection pin. It also applies this invert to existing
boards as that was the state up to this point.
Generic drivers shoud not use architecture related config options like
CONFIG_SAMV7_PWM. This commit adds PWM pin overwrite under generic
configuration option CONFIG_PWM_OVERWRITE.
Now the overwrite can be used on other architectures as well or can be
completely disabled for SAMv7.

POSIX dictates that assert() terminates via abort(), even though in NuttX
abort() just calls exit(EXIT_FAILURE) it is better to use the correct
API here, if at some point a proper implementation for abort() is made.
Also, as the kernel must not use abort() which is a userspace API, direct
the exit to PANIC() if for some reason _assert() returns (it should not
but trap it here just in case).
Remove calls to the userspace API exit() from the kernel. The problem
with doing such calls is that the exit functions are called with kernel
mode privileges which is a big security no-no.
