Subject: [PATCH v2 2/2] iio: imu: inv_mpu6050: Add support for MPU-6880
CAUTION: This email originated from outside of the organization. Please make sure the sender is who they say they are and do not click links or open attachments unless you recognize the sender and know the content is safe.
MPU-6880 seems to be very similar to MPU-6500 and it works
fine with some minor additions for the mpu6050 driver.
Add the necessary defines for it and make it use the same registers
as MPU-6500 but with a FIFO size of 4096.

I tested this on a Xiaomi Redmi 2 (or Wingtech WT88047).
Changes in v2:
- Mention support for MPU-6880 in Kconfig
