Subject: [PATCH AUTOSEL 4.19 02/12] net: mscc: ocelot: fix fields offset in SG_CONFIG_REG_3

From: Xiaoliang Yang <xiaoliang.yang_1@....com>

[ Upstream commit 4ab810a4e04ab6c851007033d39c13e6d3f55110 ]

INIT_IPS and GATE_ENABLE fields have a wrong offset in SG_CONFIG_REG_3.
This register is used by stream gate control of PSFP, and it has not
been used before, because PSFP is not implemented in ocelot driver.
