* Use rp2040-hal in all example (possibly through their bsp) Some of the examples were using the cortex_m_rt::entry method which misses the device specific spinlock re-initialisation. This commits makes the usage more consistent by using rp2040_hal exported macro as the only `entry` method used across examples.
