SPI subsystem update

[Bart Veer <bartv@ecoscentric.com>]

A couple of the CDL descriptions mentioned the generic serial package
instead of SPI. There was a typo in the documentation. I have also
added a mention of CYG_INIT_BUS_SPI priority.

	* cdl/spi.cdl: fix descriptions in the CFLAGS_ADD and
	CFLAGS_REMOVE options
	* doc/spi.sgml: fix typo. Mention CYG_INIT_BUS_SPI priority.
