Revert "serial: ns16550: Add RX interrupt buffer support"

This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881.

As Bin Meng has tested and pointed out, we don't need the RX interrupt
for the RX buffer support at all. Just reading all available characters
into a buffer is sufficient to solve the problem with the dropped
characters upon long lines pasted into the U-Boot prompt. Since this
RX buffer support can be implemented in a generic way, without any
device specifica (e.g. for the ns16550), I'll post a new patch with
a new serial RX buffer support for DM, which all DM based serial
drivers can use.

serial: ns16550: Add RX interrupt buffer support

Pasting longer lines into the U-Boot console prompt sometimes leads to
characters missing. One problem here is the small 16-byte FIFO of the
legacy NS16550 UART, e.g. on x86 platforms.

This patch now introduces a Kconfig option to enable RX interrupt
buffer support for NS16550 style UARTs. With this option enabled, I was
able paste really long lines into the U-Boot console, without any
characters missing.

serial, ns16550: bugfix: ns16550 fifo not enabled

serial, ns16550: bugfix: ns16550 fifo not enabled

commit: 65f83802b7a5b "serial: 16550: Add getfcr accessor"
breaks u-boot commandline working with long commands
sending to the board.

Since the above patch, you have to setup the fcr register.

For board/archs which enable OF_PLATDATA, the new field
fcr in struct ns16550_platdata is not filled with a
default value ...

This leads in not setting up the uarts fifo, which ends
in problems, when you send long commands to u-boots
commandline.

Detected this issue with automated tbot tests on am335x
based shc board.

The error does not popup, if you type commands. You need
to copy&paste a long command to u-boots commandshell
(or send a long command with tbot)

Possible boards/plattforms with problems:
./arch/arm/cpu/arm926ejs/lpc32xx/devices.c
./arch/arm/mach-tegra/board.c
./board/overo/overo.c
./board/quipos/cairo/cairo.c

Revert "dm: ns16550: Add support for reg-offset property"

This reverts commit d9a3bec682f9756621615f4306718a356a3230e3.

While this is a correct change to do long term it unfortunately breaks a
number of platforms that are using pdata and not named struct members so
they are getting all of their data after 'base' incorrect.
