HAL_EXTI_RegisterCallback in STM32CubeExpansion_BLE1_V4.2.0 examples references wrong core

[frackers]

The file stm32f4xx_hal_exti.c (of which there are multiple copies in the BLE tree) refers to CM7 CPU which is obviously not an F4xx.

Is this a file that escaped from the main HAL code or is it just badly written?
