can: m_can: update to support CAN FD features

Bosch M_CAN is CAN FD capable device. This patch implements the CAN
FD features include up to 64 bytes payload and bitrate switch function.
1) Change the Rx FIFO and Tx Buffer to 64 bytes for support CAN FD
   up to 64 bytes payload. It's backward compatible with old 8 bytes
   normal CAN frame.
2) Allocate can frame or canfd frame based on EDL bit
3) Bitrate Switch function is disabled by default and will be enabled
   according to CANFD_BRS bit in cf->flags.
