Update `ssd1306_write_default` to take into account the `segment_offset`
property. This is needed for some displays to show the image correctly.

Necessary for supporting for EastRising 0.42 OLED display/board.
Some boards don't have external Iref set up. This is probably done in an
effort to save on component cost. This command is only documented in the
V1.1 revision of the SSD1306 datasheet.

- Removed unused variables from the data struct
- Set all members of capability struct in `ssd1306_get_capabilities`
instead of zeroing it. This has the same effect but saves some bytes.
- Removed empty log

This allows to invert the display at runtime using the function
`ssd1306_set_pixel_format`. The current format is stored in the data
struct.
Also adjusted `ssd1306_get_capabilities` to return both supported
formats and the current one.
From the ssd1306 doc: 'In normal display a RAM data of 1 indicates an
"ON" pixel while in inverse display a RAM data of 0 indicates an "ON"
pixel.' Thus `PIXEL_FORMAT_MONO01 == SSD1306_SET_NORMAL_DISPLAY`.

Determine sh1106 from the `compatibility` value instead of
the SSD1306_CONTROLLER_TYPE setting.
Change the settings in `boards/shields/ssd1306/sh1106_128x64.overlay`
to follow this change.
Remove the SSD1306_CONTROLLER_TYPE from its Kconfig.defconfig,
and set the `compatibility` to `sinowealth,sh1106`.

Seems like the SSD1306 controller needs a bit of time after power up
before it can take i2c commands. This causes problems with
microcontrollers that have no other delays in the startup sequence, like
rpi_pico.
There's currently no good way of modeling this in Zephyr right now, and
there's also no clear indication of how much time the device needs in
the datasheet that I could find, but it seems like 10ms is enough for
that to start reliably so add a delay in the ssd1306 init function to
ensure that at least that time has passed from system power up.

It is undesirable referencing to cfb.h because it form

This introduces a new kconfig CONFIG_DISPLAY_INIT_PRIORITY
to specify the initialization priority for display devices.
Most of the display devices are using APPLICATION and
CONFIG_APPLICATION_INIT_PRIORITY which is not entirely
appropriate for devices. Due to linking order, the display
device may be initialized after application code at same
init level and priority. This results in the display device
not ready to be used for application code. So this kconfig
option allows the display devices to be initialized earlier
if needed.
For the drivers using CONFIG_APPLICATION_INIT_PRIORITY,
they have been changed to use CONFIG_DISPLAY_INIT_PRIORITY
instead.
Note that the default value for CONFIG_DISPLAY_INIT_PRIORITY
is the same as CONFIG_APPLICATION_INIT_PRIORITY at 90 to
avoid any functional changes.
