The initLCD function had the options of the function set instruction
hard coded, and thus would cause issues while initializing screens with
one line. This commit resolves this issue by checking the value of
LCD_NUMBER_OF_LINES at compile time and creating a macro LCD_LINES with
the appropriate bitmask for INSTR_FUNC_SET_N set or clear which is then
used during the definition of the initLCD function.
