1be37d3b04 can: m_can: fix periph RX path: use rx-offload to ensure skbs are sent from softirq context
For peripheral devices, m_can sent skbs directly from a threaded irq
instead of from a softirq context, breaking the tcan4x5x peripheral
driver completely. This patch transitions the driver to use the
rx-offload helper for peripherals, ensuring the skbs are sent from the
correct context, with h/w timestamping to ensure correct ordering.

ac33ffd3e2 can: m_can: let m_can_class_allocate_dev() allocate driver specific private data
This patch enhances m_can_class_allocate_dev() to allocate driver specific
private data. The driver's private data struct must contain struct
m_can_classdev as its first member followed by the remaining private data.

78e19a2926 can: m_can: m_can_config_endisable(): mark as static
The function m_can_config_endisable() is not used outside of the m_can driver,
so mark it as static.
