VGA defineds the extended ASCII set based on CP437, but there is a bug
on printing them: in vga_write_at_offset(), we perform a bitwise or
between 'unsigned short' and 'signed char':
```
p[i] = 0x0F00 | string[i];
```
If we want to show an extended ASCII character, string[i] will be
negative and this bitwise operation will fail due to their implicit
casting rule: convert signed char to unsigned short by adding 65536.
To fix this, we need to cast the string to unsigned char manually
somewhere. Since we still want to leverage the built-in string utilities
which only accepts const char*, we still preserve the original
prototypes before, and cast it until we write into the frame buffer.

The Alder Lake PEIM graphics driver executed as part of the FSP does
not wait for the panel power cycle to complete before it initializes
communication with the display. It can result in AUX channel
communication time out and PEIM graphics driver failing to bring up
graphics.
If we have performed some graphics operation in romstage, it is
possible that a panel power cycle is still in progress. To prevent any
issue with the PEIM graphics driver it is preferable to ensure that
panel power cycle is complete.

We were using the libgfxinit `Initialize' function with the
`Clean_State' parameter because the more appropriate `Update_Output'
function was not performing all the necessary clean up operations for
the PEIM driver to be successful when libgfxinit was used in romstage.
Thanks to a lot of experiments and some log analysis efforts, we were
able to identify the missing operation and fix the `Update_Output'
function (cf. https://review.coreboot.org/c/libgfxinit/+/72123).
The `initialized' global variable is now unnecessary as we track the
initialization in the Ada code instead.
Since the `Update_Output' function does not return any value, this
patch modifies the `gma_gfxstop' prototype accordingly. This does not
have any impact as the return value was not used anyway.

The current limitation with multiline message is that,
vga_line_write() function is unable to understand newline character
hence, eventually output multiple lines separated with a newline
character with a single line statement.
This patch ensures to parse the entire string and split it into
multiple lines based on the newline character and print each line
separately to the VFG framebuffer.
User can choose to align the output video message as per given choice
between left/center/right of the screen
(i.e. enum VGA_TEXT_ALIGNMENT ).
Additionally, added macros to define the horizontal screen alignment
as well. Ideally if user would like to print the video message at the
middle of the screen then the vertical alignment would be
`VGA_TEXT_CENTER` and horizontal alignment would be
`VGA_TEXT_HORIZONTAL_MIDDLE`.

When PTN3460_EARLY_INIT is selected, the PTN3460 (DP-2-LVDS-bridge) will
be initialized before all devices are initialized. This is necessary to
get a valid EDID data set into the PTN3460 before the graphic controller
is initialized in order to be able to show a splash screen.
For ptn3460_init() to work properly the I2C bus this bridge is connected
to needs to be initialized. As this I2C bus initialization would be done
too late in the normal flow, it needs to be called here explicitly
before ptn3460_init() to initialize the I2C bus with the needed
conditions. Otherwise the default I2C settings of the controller will be
used which results in a clock rate too high for this mainboard.
Test=Measure I2C bus signals and make sure that the clock is <= 400 kHz.

now fillin those platform specific data using SoC specific macros.
