armv8: ls1046ardb: Add falcon mode for for QSPI boot
A new defconfig is introduced to support SPL boot from QSPI NOR
flash. This is to support falcon mode for faster booting into
Linux.

The "loadables" is not optional. It tells SPL which images to load into memory.
+Falcon mode with QSPI boot
+--------------------------
+To use falcon mode with QSPI boot, SPL needs to be enabled. Similar to SD or
+NAND boot, a RAM version full feature U-Boot is needed. Unlike SD or NAND boot,
+SPL with QSPI doesn't need to combine SPL image with RAM version image. Two
+separated images are used, u-boot-spl.pbl and u-boot.img. The former is SPL
+image with RCW and PBI commands to load the SPL payload into On-Chip RAM. The
+latter is RAM version U-Boot in FIT format (or legacy format if FIT is not
+used).
+
Other things to consider
-----------------------
Falcon boot skips a lot of initialization in U-Boot. If Linux expects the
