phy: renesas: rcar-gen3-usb2: Fix sysfs interface of "role"
commit 4bd5ead82d4b877ebe41daf95f28cda53205b039 upstream.
Since the role_store() uses strncmp(), it's possible to refer
out-of-memory if the sysfs data size is smaller than strlen("host").
This patch fixes it by using sysfs_streq() instead of strncmp().
