[PATCH] doc: drop recommendation against bool in structures

The coding style advised against bool in structures, citing space and
type-size concerns inherited from the Linux kernel. That does not match
DPDK practice: bool is already used in over 1400 structure fields across
the tree, including core APIs such as rte_flow. Drop the note so the
style guide reflects actual usage.

 * Use of the structures should be by separate variable declarations and those declarations must be extern if they are declared in a header file.
 * Externally visible structure definitions should have the structure name prefixed by ``rte_`` to avoid namespace collisions.
 
-.. note::
-
-    Avoid using ``bool`` in structures because it wastes space and
-    the type size is unclear. A preferred use of
-    ``bool`` is mainly as a return type from functions that return true/false,
-    and maybe local variable functions.
