Summary: Add support for at89Sx051 chips

Initial Comment:
I have created a header file (attached) that includes the extensions to the at89Cx051 that the at89Sx051 chips provide. The data sheet is at <http://www.atmel.com/dyn/resources/prod_documents/doc3390.pdf> and the differences between the two series is at <http://www.atmel.com/dyn/resources/prod_documents/doc3554.pdf>. There is another interrupt on 0x00, but it doesn't fit the 8*n+3 rule and I'm guessing all 8051 chips have that interrupt anyways and that you can't do much about it.
