NuttX only treat \n as new line after https://github.com/apache/nuttx/pull/8628,
so need this conversion to interact with terminal emulator.

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.

mmcsd_removed will be called if the card is in invalid state.
This can happen if the card is bad, or vibrations causes a power
loss.
mmcsd_removed resets:
priv->capacity = 0; /* Capacity=0 sometimes means no media */
priv->blocksize = 0;
priv->probed = false;
priv->mediachanged = false;
priv->wrbusy = false;
priv->type = MMCSD_CARDTYPE_UNKNOWN;
priv->rca = 0;
priv->selblocklen = 0;
priv->widebus = false;
If blocksize is set to 0 will cause the log2 to result
in an infinate loop in some drivers.
IS_EMPTY will check for priv->type = MMCSD_CARDTYPE_UNKNOWN
and return ENODEV.
The TERMIOS(3) function tcsendbreak() and the IOCTLs TCSBRK and TCSBRKP
transmit a serial line Break.
Previously NuttX included an extern declaration for tcsendbreak() and
defines for TCSBRK and TCSBRKP but none of these were implemented.
Attempting to build programs that called tcsendbreak() would fail with
a linker error; attempting to use TCSBRK and TCSBRKP would result in an
error at runtime.
This changeset adds the tcsendbreak() function and handling for TCSBRK
and TCSBRKP; tcsendbreak() is implemented in terms of TCSBRK. Both
TCSBRK and TCSBRKP are implemented in terms of the BSD-compatible Break
IOCTLs TIOCSBRK and TIOCCBRK, which must be provided by the lower half
serial driver. Currently, not all lower half serial drivers in NuttX
support these IOCTLs. Those that do implement them may need one or more
Kconfig options to be set, such as `CONFIG_*_U[S]ART_BREAKS` and, on
some architectures, a separate `CONFIG_*_SERIALBRK_BSDCOMPAT`.
* drivers/serial/serial.c
(uart_tcsendbreak): New function.
(uart_ioctl): Implement TCSBRK and TCSBRKP.
* libs/libc/termios/lib_tcsendbreak.c
(): New file.
* libs/libc/termios/Make.defs
(CSRCS): Add lib_tcsendbreak.c to the build.
Thanks to Xiang Xiao for PR feedback.

First decoupling changes related to CMAKE
BINDIR/APPSBINDIR:
Output path of Kconfig which dynamically generated by NuttX Kernel/Apps
This option is consistent with the TOPDIR/APPSDIR by default, and will
be changed when out-of-tree compilation is supported
