As part of an SMP cleanliness pass over UML, I consted a bunch of
structures in order to not have to document their locking.  One of these
structures was a struct tty_operations.  In order to const it in UML
without introducing compiler complaints, the declaration of
tty_set_operations needs to be changed, and then all of its callers need to
be fixed.

This patch declares all struct tty_operations in the tree as const.  In all
cases, they are static and used only as input to tty_set_operations.  As an
extra check, I ran an i386 allyesconfig build which produced no extra
warnings.

53 drivers are affected.  I checked the history of a bunch of them, and in
most cases, there have been only a handful of maintenance changes in the
last six months.  serial_core.c was the busiest one that I looked at.

The Compaq TC1000 and Fujitsu Stylistic range of tablet machines use
touchscreens from FPI. These are implemented as serial interfaces,
generally exposed in the ACPIPNP information on the system. This patch
adds them to the 8250_pnp driver tables, avoiding the need to mess
around with setserial to set them up.

I haven't been able to confirm what FUJ02B5, FUJ02BA and FUJ02BB are.
FUJ02B1 refers to the controller for the system hotkeys. FUJ02BC appears
to be the last in the range - after this, they moved to Wacom-based
systems.

A serial card might have been removed when the system is resumed.
This results in a suspended port being shut down, which results in
the ports shutdown method being called twice in a row.  This causes
BUGs.  Avoid this by tracking the suspended state separately from
the initialised state.

and replaces SERIAL_PORT_DFNS with its own driver private copy.

The fs_no mean used to be fs_enet driver driven, hence it was an
enumeration across all the possible fs_enet "users" in the SoC. Now, with
QE on the pipeline, and to make DTS descriptions more clear, fs_no features
relevant SoC part number, with additional field to describe the SoC type.

Another reason for that is now not only fs_enet is going to utilize those
stuff. There might be UART, HLDC, and even USB, so to prevent confusion and
be ready for upcoming OF_device transfer, fs_enet and cpm_uart drivers were
