u-boot: ae350-ax45mp: Add patch for fdt start address alignment

Browse Source 
If start address ($a1) is not 8-byte aligned, the system will hang in
fw_platform_init where OpenSBI starts to parse fdt, thus need this patch
to adjust the address in SPL.

Subject: [PATCH] spl: Align device tree blob address at 8-byte boundary
Since libfdt v1.6.1, a new requirement on the device tree address via:
commit 5e735860c478 ("libfdt: Check for 8-byte address alignment in fdt_ro_probe_()")
must be met that the device tree must be loaded in to memory at an
8-byte aligned address.
