the FAULT_LOG register is on linux side always 0x0 regardless

There are two new validation boards: LPDDR4 board (30123) and DDR3L board (30010)
for imx8x family 17x17 chips. These two boards have same design except the DDR.
Since SCFW is resposible for DDR initialization, U-boot could use one build to
cover two boards.
The 8DX 17x17 DDR3L ARM2 has been added into u-boot before, so we rename the config
CONFIG_TARGET_IMX8DX_DDR3_ARM2 to CONFIG_TARGET_IMX8X_17X17_VAL to cover DDR3L and
LPDDR4.
Considering 8DX and 8QXP 17x17 may solder to the boards, we create two defconfig:
one for DX and another for 8qxp to share with the CONFIG_TARGET_IMX8X_17X17_VAL
but with different FDTs.

To support partition reboot, the u-boot has to enable clocks by LPCG.
The LPCG will reset to default value only when the subsystem is totally
power off and reset. However, the resources in one subsystem may belong
to different partitions, so the partition reboot may not reboot the entire
subsystem.
Powers, clocks/lpcg, GPR, IP may not reset depends on various cases and
HW design. Thus, AP software has to ensure everything is reset by SW
itself to support such above cases.
