can: flexcan: add support for timestamp based rx-offload The flexcan IP core has 64 mailboxes. For now they are configured for RX as a hardware FIFO. This FIFO has a fixed depth of 6 CAN frames. In some high load scenarios it turns out thas this buffer is too small. In order to have a buffer larger than the 6 frames FIFO, this patch adds support for timestamp based offloading via the generic rx-offload infrastructure.
