[PATCH 6/7] ARM: stm32mp: init: don't print STM32MP15 CPU type

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

TF-A already reads the OTP and unconditionally prints at a higher log
level:

  NOTICE:  CPU: STM32MP157AAA Rev.B

barebox reads the OTP again via the secure monitor only to print:

  stm32mp-init: detected STM32MP157AAA Rev.B

which doesn't add any extra information, so drop it.
