MLK-13141 mx6qpsabresd: Do not touch VGEN3 and VGEN5
VGEN3 and VGEN5 have been fused the right value in PF0100 on i.mx6qp board, so software didn't need to change their voltage output anymore. Otherwise, VGEN3 will be wrongly updated from 1.8v to 2.8v. Signed-off-by: Robin Gong <yibin.gong@nxp.com> (cherry picked from commit 6f7f185664a401f03f6ce6c81b996c1f27fdbe73)
