hd44780: Make the 4-bit init sequence more robust
The previous init sequence relied on the display ignoring commands if
they are sent faster than 40us. Some displays may not have this
limit.
Rework the init to make it more robust to command transmission times.
The new init should still transition the display into 4-bit mode even
if the display processes commands faster than 40us.
