[DISK-LAYOUT][IMX8][IMX9] Fix alignment for first partition for iMX8/iMX9 platforms
The current offset of the first partition is not aligned to the specified boundary. This can lead to invalid boot process in case the bootloader environment is saved into the device. This because the i.MX8/i.MX9x platforms, from the setting of the Silicon Vendor, require the first partition is aligned at 8192 bytes.
To do this, the variable ALIGN_FIRST_PARTITION has been set to "8192".
