[U-Boot] [PATCH v7 13/19] Makefile: u-boot-with-spl.bin: Fix SPL padding

[Benoît Thébaudeau]

PAD_TO is not a generic SPL configuration option, so use CONFIG_SPL_MAX_SIZE
instead.

We want to use --pad-to with a size, but this option expects an address, so use
u-boot-spl.bin instead of u-boot-spl as the input file in order to get addresses
starting at 0.
