kstrto*: correct documentation references to simple_strto*()

The documentation of the kstrto*() functions reference the simple_strtoull
function by "used as a replacement for [the obsolete] simple_strtoull".
All these functions describes themselves as replacements for the function
simple_strtoull, even though a function like kstrtol() would be more aptly
described as a replacement of simple_strtol().

Fix these references by making the documentation of kstrto*() reference
the closest simple_strto*() equivalent available.  The functions
kstrto[u]int() do not have direct simple_strto[u]int() equivalences, so
these are made to refer to simple_strto[u]l() instead.

Furthermore, add parentheses after function names, as is standard in
kernel documentation.
