In current implementation, any exception would trigger a CPU reset.
But a bad written SPL would cause infinite loop where the system
will reload the same SPL instead of loading factory safe image.
Hence this patch is to ensure any exception will cause a hang. At this

shall load the next production image or factory safe image.

The cfi-flash driver uses an open-coded version of the generic
algorithm to decode and translate multiple frames of a "reg" property.
This starts off the wrong foot by using the address-cells and size-cells
properties of *this* very node, and not of the parent. This somewhat
happened to work back when we were using a wrong default size of 2,
but broke about a year ago with commit 0ba41ce1b7 ("libfdt: return
correct value if #size-cells property is not present").
Instead of fixing the reinvented wheel, just use the generic function
that does all of this properly.
This fixes U-Boot on QEMU (-arm64), which was crashing due to decoding
a wrong flash base address:
DRAM: 1 GiB
Flash: "Synchronous Abort" handler, esr 0x96000044
