The original use of struct m_can_classdev::hrtimer was to support polling
for devices without IRQ, with the timer function called hrtimer_callback().
Commit 07f25091ca02 ("can: m_can: Implement receive coalescing") uses the
hrtimer for software-supported IRQ coalescence, with the timer function
called m_can_coalescing_timer().
To improve the readability of the driver, rename hrtimer_callback() to
m_can_polling_timer(), which better describes the functionality.
