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
