Implement a FSI master using GPIO. Will generate FSI protocol for
read and write commands to particular addresses. Sends master command
and waits for and decodes a slave response.
Includes changes from Edward A. James <[email protected]> and Jeremy
Kerr <[email protected]>.

depends on FSI is redundant since "if FSI" does the same thing.
Hi Randy,
Thanks for the feedback, will correct.
