Note: This patch was part of initial submission
https://lore.kernel.org/linux-arm-msm/20230329053726.14860-1-quic_kathirav@xxxxxxxxxxx/
however this got missed in between, so sending it across again.

If you're not adding a partition table, you can drop the address-
and size-cells properties, as they determine what the reg value of
the child looks like.
Sorry, somehow I missed this query. Will check and update it.
Currently IPQ boot loaders patches the partition information into the
SPI node. To parse that, we need the address-cells and size-cells
properties.
Also, this patch is now integrated into the below series
