[PATCH v4 16/16] Drop the special am335x_boneblack_vboot target

Sun Jun 23 19:53:02 CEST 2024
Now that am335x_evm boots OK on the Beaglebone black, drop the latter
and update the docs to cover the change.
Also add a few updates about 'make fit' and drop the note about the
security review, as U-Boot's verified boot has had quite extensive
review now.

Changes in v4:
- Move Binman size feature to a separate series
Changes in v2:
- Drop patch "regulator: rk8xx: Fix incorrect parameter"
- Rewrite boneblack patch to onstead drop the target and update docs
