jtag: drivers: ulink: special align switch and case statements

The coding style requires the 'case' to be at the same indentation
level of its 'switch' statement.

Checkpatch is not able to detect numbers in exponential format,
like 6E-5, and complains about missing space around the operator
minus.

To complete the alignment of switch and case statements in this
file, use a separate commit with the special checkpatch ignore tag
in the commit message.

Align the code accordingly.
