Subject: [PATCH] net: dsa: mv88e6xxx: fix boolreturn.cocci warnings

From: Fengguang Wu <fengguang.wu@...el.com>

drivers/net/dsa/mv88e6xxx/serdes.c:66:9-10: WARNING: return of 0/1 in function 'mv88e6352_port_has_serdes' with return type bool

 Return statements in functions returning bool should use
 true/false instead of 1/0.
Generated by: scripts/coccinelle/misc/boolreturn.cocci

Fixes: eb755c3f6b7d ("net: dsa: mv88e6xxx: Add helper to determining if port has SERDES")
