Invensense has already done this with the drivers they've made for the MPU925x, called Embedded MotionDriver 6.12. Just swap out the read and write implementations with applicable nRF SDK TWI/SPI driver calls.

Also note from TDK Invensense:

"Note: The MPU9250 is Not Recommended for New Designs"
You should really consider using their newer series of MPUs as they consider this a legacy product.

OK.

So remember that the Mpu925x neither knows nor cares what microcontroller you use - let alone whether you use an SDK, or what version it is.

Separate-out the parts that are specific to the SDK from the parts that are to do with the Mpu925x .

Provide a "clean" interface which is independent of SDK version - with functions like send_byte() and read_byte().

Then you will be able to incorporate your Mpu925x code into any SDK - or, in fact, onto any other microcontroller.

This is the basis of good, modular, portable software design!

But the examples in SDK 15.3.0 doesn't have MPU925sereis Examples

So why not just start with the example from that SDK ?
