pieeprom-2026-01-09: 2711: arm_loader: Apply rpifwcrypto lock permissions GET/SET USER OTP (latest)

Browse Source 
* arm_loader: Apply rpifwcrypto lock permissions GET/SET USER OTP
  Previously, the GET/SET user OTP mailboxes would provide access to the
  device unique private key. Update the mailbox API to fail if the
  key has been locked via lock_device_private_key=1 in config.txt or
  the associated mailbox call.
  GET/SET user OTP fails by setting the result tag to the standard
  error code (0x80000000). The dedicate GET/SET private key continue
  to fail the entire mailbox operation to force vcmailbox to exit
  with a non-zero error code.
* cm5: Add support for 8-bit bus width eMMC
* Query all sdram devices for temperature when adjusting refresh
* Add support for more SDRAM die configurations.
