Move CONFIG_SYS_TEXT_BASE to Kconfig, and add default values in board
Kconfig files matching what was present in their config headers. This
will make it cleaner to conditionalise the value for Malta based on 32

Make use of device model & device tree to probe the UART driver. This is
the initial step in bringing Malta up to date with driver model, and
allows for cleaner handling of the different I/O addresses for different
system controllers by specifying the ISA bus address instead of a
translated memory address.

The address of the UART differs based upon the system controller because
it's actually within the I/O port region, which is in a different
location for each system controller. Rather than handling this as 2
UARTs with the correct one selected at runtime, use I/O port accessors
for the UART such that access to it gets translated into the I/O port
region automatically.

Add option to set shell prompt string from menuconfig and migrate
boards globally.
The migration is done as follows:
- Boards that explicitly and unconditionally set CONFIG_SYS_PROMPT had the
entry moved to their defconfig files.
- Boards that defined some kind of #ifdef logic which selects the
CONFIG_SYS_PROMPT (for example qemu-mips) got an #undef CONFIG_SYS_PROMPT
right before the #ifdef logic and were left alone.
- This change forces CONFIG_SYS_PROMPT to be a per board decision, and thus
CONFIG_SYS_PROMPT was removed from all <soc>_common.h and <arch>_common.h
files. This results in a streamlined default value across platforms, and
includes the following files: spear-common, sunxi-common, mv-common,
ti_armv7_common, tegra-common, at91-sama5_common, and zynq-common.
- Boards that relied on <arch/soc>_common.h values of CONFIG_SYS_PROMPT were
not updated in their respective defconfig files under the assumption that
since they did not explicitly define a value, they're fine with whatever
the default is.
- On the other hand, boards that relied on a value defined in some
<boards>_common.h file such as woodburn_common, rpi-common,
bur_am335x_common, ls2085a_common, siemens_am33x_common, and
omap3_evm_common, had their values moved to the respective defconfig files.
- The define V_PROMPT was removed, since it is not used anywhere except for
assigning a value for CONFIG_SYS_PROMPT.

CONFIG_SYS_NS16550_CLK specifies the rate of the clock 16x the baud
rate. The SMSC FDC37M81x datasheet states that a divider of 1 results in
a UART at 115200 baud, thus the x16 clock rate is 115200 * 16.
Previously the divider was left at 0 which led to a rate of 38400 baud
regardless of CONFIG_BAUDRATE or the baudrate environment variable.

The physical base address of the NOR flash is 0x1e000000
on the Malta boards. The hardware also maps the first 4MiB
of the flash into the 0x1fc00000-0x1fffffff range.
Currently, U-Boot uses the mapped address to access the
flash, which does not work in recent qemu versions.
Since commit a427338b222b43197c2776cbc996936df0302f51
(mips_malta: correct reading MIPS revision at 0x1fc00010)
writing to the mapped address space causes a CPU exception.
Due to the exception, U-Boot hangs during boot when it tries
to detect the CFI flash chip.
Use the correct physical address for the MALTA_FLASH_BASE
constant to fix the problem. In order to avoid relocation
problems, also update the CONFIG_SYS_{TEXT,MONITOR}_BASE
constants.
The change makes it possible to start U-Boot on a Malta
board emulated with Qemu 1.6.1 and 1.7.0-rc0. It also
works on older versions (tested with 1.1.1, 1.2.2, 1.4.2,
1.5.3).

This patch adds support for running on Malta boards using coreFPGA6
core cards, including support for the msc01 system controller used
with them. The system controller is detected at runtime allowing one
U-boot binary to run on a Malta with either.
Due to the PCI I/O base differing between Maltas using gt64120 & msc01
system controllers, the UART setup is modified slightly. A second UART
is added so that there is one pointing at the correct address for each
system controller. The Malta board then defines its own
default_serial_console function to select the correct one at runtime.
The incorrect UART will simply not function.
Tested on:
- A coreFPGA6 Malta running interAptiv and proAptiv bitstreams, both
with and without an L2 cache.
- QEMU.
