d622b09bc0 samples: tests: remove obsolete KERNEL_TYPE and kernel variables 
Remove those from Makefiles and testcase.ini, we now support unified kernel
only and sanitycheck script now knows how to deal with this.

3a8d3dd07d samples: lcd_hd44780: use unified kernel 
Use unified kernel for lcd hd44780 app.

Some delays were rounded up to multiples of millisecond, since
k_sleep only takes multiples of millisecond. Based on the lcd
datasheet, this should not cause any problem.

updated some comments based on what the code is actually doing.

7254f1d168 samples: gpio: lcd: sample app for HD44780 LCD controller 
Display text strings on parallel interfacing HD44780 based
    generic LCD controller using GPIO pins to interface with
    Arduino Due(SAM3). HD44780 is a popular controller and an
    example can help using gpio pins in parallel with it. I
    have tested it on JHD20x4 LCD panel for 4Bits & 8Bits
    configuration. The code has been made generic so that user
    can modify quite a few options.
