This series updates the build support for k3 devices to use rsa degenerate
key. This significantly improves the boot time. While at it update the
timeout for initializing system controller which cover a valid boot scenario.

TI's K3 boot architecture mandates a x509 certificate for every boot image.
While signing the image K3 ROM allows for two types of keys based on which
the boot image gets loaded in different ways:
- Degenerate RSA keys: This generates a signature which is equal to the digest.
When ROM sees this, it does a DMA for copying the images,
which significantly improves the boot time.
- Any other key: Does a memcpy to load the image. This is introduced as a
fallback for DMA copy.
Add a script for generating boot images with the above options. Default
generates image using rsa degenerate key in order to improve boot time.

Instead of overlading makefile, use the k3_gen_x509_cert.sh script
to generate boot images.

There is one case where 400ms is not sufficient for loading the
system firmware:
- System firmware is not signed with rsa degenerate key.
- ROM loading the sysfw directly from SPI flash which is in memory
mapped mode.
The above scenario is definitely not desired in production use cases
as it effects boot time. But still keeping this support as this is
a valid boot scenario.
