Adds serdev_device_break_ctl() and an implementation for ttyport. This function simply calls the break_ctl in tty layer, which can assert a break signal over UART-TX line, if the tty and the underlying platform and UART peripheral supports this operation.

termios: get rid of non-UAPI asm/termios.h
All non-UAPI asm/termios.h consist of include of UAPI counterpart and, possibly, include of linux/uaccess.h
The latter can't be simply removed, even though nothing in linux/termios.h doesn't depend upon it anymore - there are several places that rely upon that indirect chain of includes to pull linux/uaccess.h. So the include needs to be lifted out of there - we lift into tty_driver.h, serdev.h and places that pull asm/termios.h, but none of * linux/uaccess.h (obvious) * net/sock.h (pulls uaccess.h) * linux/{tty,tty_driver,serdev}.h (tty.h pulls tty_driver.h)
That leaves us just with the include of UAPI asm/termios.h, which is what <asm/termios.h> will resolve to if we simply remove non-UAPI header.

serdev: BREAK/FRAME/PARITY/OVERRUN notification prototype V2
Allow serdev device drivers get notified by hardware errors such as BREAK, FRAME, PARITY and OVERRUN.
With this patch, in the event of an error detected in the UART device driver the serdev_device_driver will get the newly introduced ->error() callback invoked if serdev_device_set_error_mask() has previously been used to enable the type of error. The errors are taken straight from the TTY layer and fed into the serdev_device_driver after filtering out only enabled errors.
Without this patch the hardware errors never reach the serdev_device_driver.

Note that this is based on the requirements and characteristics of the tty-port controller implementation which receives data in workqueue context and whose write_wakeup callback must not sleep.

serdev: fix receive_buf return value when no callback
The receive_buf callback is supposed to return the number of bytes processed and should specifically not return a negative errno.
Due to missing sanity checks in the serdev tty-port controller, a driver not providing a receive_buf callback could cause the flush_to_ldisc() worker to spin in a tight loop when the tty buffer pointers are incremented with -EINVAL (-22).
The missing sanity checks have now been added to the tty-port controller, but let's fix up the serdev-controller helper as well.

tty/serdev: add serdev registration interface
Add a new interface for registering a serdev controller and clients, and a helper function to deregister serdev devices (or a tty device) that were previously registered using the new interface.
Once every driver currently using the tty_port_register_device() helpers have been vetted and converted to use the new serdev registration interface (at least for deregistration), we can move serdev registration to the current helpers and get rid of the serdev-specific functions.

serdev: Add serdev_device_write subroutine
Add serdev_device_write() a blocking call allowing to transfer arbitraty amount of data (potentially exceeding amount that serdev_device_write_buf can process in a single call)
To support that, also add serdev_device_write_wakeup().
Drivers wanting to use full extent of serdev_device_write functionality are expected to provide serdev_device_write_wakeup() as a sole handler of .write_wakeup event or call it as a part of driver's custom .write_wakeup code.
Because serdev_device_write() subroutine is a superset of serdev_device_write_buf() the patch re-impelements latter is terms of the former. For drivers wanting to just use serdev_device_write_buf() .write_wakeup handler is optional.

serdev: Introduce new bus for serial attached devices
The serdev bus is designed for devices such as Bluetooth, WiFi, GPS and NFC connected to UARTs on host processors. Tradionally these have been handled with tty line disciplines, rfkill, and userspace glue such as hciattach. This approach has many drawbacks since it doesn't fit into the Linux driver model. Handling of sideband signals, power control and firmware loading are the main issues.
This creates a serdev bus with controllers (i.e. host serial ports) and attached devices. Typically, these are point to point connections, but some devices have muxing protocols or a h/w mux is conceivable. Any muxing is not yet supported with the serdev bus.
