spi: Make 'default_spi_send_multicommand' the default unless defined
A NULL func pointer is necessary and sufficient for the
condition `NULL func pointer => default_spi_send_multicommand' as to not
need this explicit specification of 'default'.
Therefore drop the explicit need to specify the
'default_spi_send_multicommand' callback function pointer in the
spi_master struct. This is a reasonable default for every other driver
in the tree with only a few exceptions.
This simplifies the code and driver development.
