ENGR00315894-61 iMX6SX: Add MX6SX 17x17 ARM2 board support

Add BSP codes for iMX6SX 17x17 ARM2 board to support SD/MMC,
USB, QSPI2 NOR Flash, SPI NOR flash, NAND Flash, Ethernet, I2C
,PMIC and M4 command boot (bootaux).

Some features has conflicts, so can't be enabled at same time:
    QSPI <--->  NAND                pin conflict
    QSPI <--->  SPI-NOR             u-boot driver conflict
    SPI-NOR <---> SD2               pin conflict

Add board build targets of 17x17 ARM2 for boot device:
    mx6sx_17x17_arm2        --- SD/MMC/eMMC
    mx6sx_17x17_arm2_spinor --- SPINOR on ECSPI4 CS0
    mx6sx_17x17_arm2_nand   --- NAND flash
    mx6sx_17x17_arm2_qspi2  --- QuadSPI2 NOR flash
