can: m_can: m_can_set_bittiming(): fix setting M_CAN_DBTP register
This patch fixes the setting of the M_CAN_DBTP register contents:
- use DBTP_ (the data bitrate macros) instead of NBTP_ which area used
for the nominal bitrate
- do not overwrite possibly-existing DBTP_TDC flag by ORing reg_btp
instead of overwriting
