This patch writes the default values for TXTL and RXTL to UARTx_UFCR.
Without this patch some older kernel versions crash as UARTx_UFCR was
not always correctly initialized.

For platforms that don't use device tree in SPL the only way to mark this
driver as 'required by relocation' is with the DM_FLAG_PRE_RELOC flag. Add
this to ensure that the driver is bound.

Change reg-shift property default to zero. When the integer property
is missing, it should be taken as zero. This is consistent to Linux
drivers/tty/serial/of_serial.c.
The x86 and most powerpc use reg-shift of 0. Most others use reg-shift
of 2. While reg-shift of 1 is rarely used.

Add generic binding to unify ns16550 drivers. There are
several drivers using almost the same code, such as serial_dw,
serial_keystone, serial_omap, serial_ppc, serial_rockchip,
serial_tegra.c, and serial_x86. But each is platform specific.
The key difference between these drivers is the way to get
input clock frequency. With this unified approach, fixed clock
frequency should be extracted from "clock-frequency" property of
device tree blob. If this property is not available, the macro
CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a
function to get clock, eg, get_serial_clock().

Change map_sysmem() to map_physmem(,,MAP_NOCACHE). Though map_sysmem()
can be used to map system memory, it might be wrong to use it for I/O
ports. The map_physmem() serves the same purpose to translate physical
address to virtual address with the additional flag to take care of cache
property. Most drivers use map_physmem() since I/O ports access should be
uncached. As ns16550 is a driver, it should use map_physmem() rather
than map_sysmem().

Some boards need to set things up before the debug UART can be used. On
these boards a call to debug_uart_init() is insufficient. When this option
is enabled, the function board_debug_uart_init() will be called when
debug_uart_init() is called. You can put any code here that is needed to
set up the UART ready for use, such as set pin multiplexing or enable
clocks.

This arch does not seem to be supported / used at all in the current
U-Boot mainline source tree any more. So lets remove the core u8500 code
and code that was only referenced by this platform.
Please note that this patch also removes these config options:
- CONFIG_PL011_SERIAL_RLCR
- CONFIG_PL011_SERIAL_FLUSH_ON_INIT
As they only seem to be referenced by u8500 based boards. Without any
such board in the current code, these config option don't make sense
any more. Lets remove them as well.
If someone still wants to use this platform, then please send patches
to re-enable support by adding at least one board that references this
code.
