Subject: [PATCH 0/4] R-Car CANFD Improvements

The calculation formula for nominal bit rate of classical CAN is same as
that of nominal bit rate of CANFD on the RZ/G3E SoC compared to other SoCs.
Add shared_bittiming variable to struct rcar_canfd_hw_info to handle this
difference.

Added the patch "Drop unused macros" to this serires.

Apart from this, replaced the RCANFD_NCFG_* and RCANFD_DCFG_* macros
with simple functions and replaced RCANFD_CFG_* macros with FIELD_PREP
macro.
