ULINK driver and OpenULINK firmware: whitespace and comment fixes (trivial)

ULINK driver and OpenULINK firmware: whitespace and comment fixes (trivial)

In commit de0130a0aad83c1ef692ee4d68ab996a8668424d, some doxygen documentation
blocks of the form "///< ..." (documentation after member) got changed to
"/* /< ...", which is not recognized by doxygen. This commit changes them to
the correct form "/**< ...".

Also, remove some leading whitespace characters and fix alignment of comment
blocks where appropriate.
