pieeprom-2025-10-03: 2711: arm_dt: Report OTP SDRAM size via device-tree (latest)

* arm_dt: Report OTP SDRAM size via device-tree
  Report the SDRAM in gigabits via device-tree as
  /proc/device-tree/chosen/rpi-sdram-size-gbit. Scripts reporting the
  device-capabilities should use this value (if defined) instead of the
  memory-size field in the boardrev row.
* Apply UART_BAUD in early bootsys UART init
  Update bootsys and fatal error handlers to use the user
  defined UART_BAUD rate.
* rpifwcrypto: Add support for ECDSA P-256 key generation
  Also, slightly improve the entropy by passing the system
  timer value as the personality string.
