Add a static u-boot config for i.MX93 low drive mode support. When low drive mode is enabled, VDD_SOC is set to 0.75V. Bus clocks, A55 core clock (900Mhz), DDR clock (1866MTS), and some peripherals clocks (USDHC/FLEXSPI/PDM/DISP_PIX/CAM_PIX) must decrease to meet max frequencies in low drive mode. Also set standby voltage for buck1 Signed-off-by: Ye Li <ye.li@nxp.com> Signed-off-by: Peng Fan <peng.fan@nxp.com>
