drivers/: Make 'internal_delay' the default unless defined

Drop the explicit need to specify the default 'internal_delay'
callback function pointer in the programmer_entry struct.
This is a reasonable default for every other driver in the
tree with only the two exceptions of ch341a_spi.c and serprog.c.

Thus this simplifies driver development.
