5.15-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit e64285ff41bb7a934bd815bd38f31119be62ac37 ]
Since '1 << rocker_port->pport' may be undefined for port >= 32, cast the left operand to 'unsigned long long' like it's done in 'rocker_port_set_enable()' above. Compile tested only.
