[PATCH v2 03/14] ARM: k3: r5: drop loading of separate binaries

[Sascha Hauer <s.hauer@pengutronix.de>]

For starting the A52 cores we need TFA, OP-TEE, barebox and ti-dm
binaries. These can be loaded as separate files from SD/eMMC/DFU or
alternatively combined into a single FIP image.
FIP images are convenient to handle, they can easily be generated on the
command line and fiptool also has support for replacing blobs in images.
This makes handling of separate binaries rather unnecessary and support
for it only makes the loading code more complex. Drop it and make FIP
images the only option which also faciliates integrating of secure boot.
