MPU-6886 Incorrect I2C register set- may be harmless

[ed-french]

The driver has been handy thanks! In making some changes for my particular application I noticed something odd with a register set. Is it intentional, or was something else intended?

In MPU6886.cpp register MPU6886_INT_PIN_CFG (0x37) is set to 0x22. So setting to 1 the bit1 position.

However the datasheet https://m5stack.oss-cn-shenzhen.aliyuncs.com/resource/docs/datasheet/core/MPU-6886-000193%2Bv1.1_GHIC_en.pdf suggests the bottom bits are Reserved.

What was intended?

Thanks again.
