The ABR and secure boot states are currently controlled by the
"emmc-abr" and "signing-settings" machine properties.
On real hardware, these states are determined by the OTP configuration
and reflected in the SBC status registers. This series updates the
model to derive the ABR and secure boot states from OTP instead, and
removes the corresponding machine properties.
The series also consolidates the OTP layout definitions and adds
helpers for reading OTP configuration and strap settings.
Any feedback or suggestions are appreciated!
