Hi! I was testing the CC1352P Launchpad and I2C pins are good. 👍 > i2c_read_reg 0 85 6 0

Contribution description
The CC26xx/CC13xx MCUs have only a single I2C interface, and has not changed between x0/x2 revisions, it's exactly the same (the SDK is using the same exact code).
Only 100 kbit/s mode is supported, fast mode (400 kbit/s) is up to another PR.
Testing procedure
cc26x0boards should still have a working I2C (no code is touched in reality).cc26x2/cc13x2boards should be able to runtests/periph_i2ccorrectly with a known working device. Please note that this device has weak pull-up resistors.Issues/PRs references

cc @luisan00, could you check if the pins for CC1352P launchpad are good?
