'putarea' function now has to select the appropriate values from the
whole frame buffer instead of the previous expectation of having just
specified rectangle passed to it.
This required extension of WRRAM handling function as we now are not
writing simply buffer but we want to skip some values and do that
multiple times. Having two implementation in this case is worst as this
function is actually called only twice in the whole code (thus making
dedicated function for every call if we would have two variants).
Calling `st7789_wrram` multiple times is not an option as command
ST7789_RAMWR resets the position and thus calling it multiple times just
overwrites the previous values.
In order to support multiple LCD instances per board, add a pointer from
lcd_planeinfo_s to the lcd_dev_s which it belongs to. Also enhance the
putrun, getrun, putarea and getarea methods to pass through the
lcd_dev_s pointer to the respective device driver.
Port all LCD device drivers to this lcd_planeinfo_s extension.
Enhance SSD1306 driver to support multiple LCDs.

Make sending commands independent of processor endianness. The data can
be handled by application side, such as LVGL has SWAP16 option.
