staging: iio: Documentation: rewrite the right hand side of an assignment

Author: Aya Mahfouz <mahfouz.saif.elyazal@gmail.com>

This patch rewrites the right hand side of an assignment for
expressions of the form:
a = (a  b);
to be:
a = b;
where  = << | >>.

This issue was detected and resolved using the following
coccinelle script:

@@
identifier i;
expression e;
@@

-i = (i >> e);
+i >>= e;

@@
identifier i;
expression e;
@@

-i = (i << e);
+i <<= e;
