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 and R-Car Gen4
compared to other SoCs. Update the nominal bit rate constants.

Apart from this, for replacing function-like macros, introduced
rcar_canfd_compute_{nominal,data}_bit_rate_cfg().

v2->v3:
 * Replaced "shared_bittiming"->"shared_can_regs" as it is same for RZ/G3E
   and R-Car Gen4.
 * Updated commit header and description for patch#1.
 * Added Rb tag from Geert for patch #2,#3 and #4.
 * Dropped _MASK suffix from RCANFD_CFG_* macros.
 * Dropped _MASK suffix from RCANFD_NCFG_NBRP_MASK macro.
 * Dropped _MASK suffix from the macro RCANFD_DCFG_DBRP_MASK.
 * Followed the order as used in struct can_bittiming{_const} for easy
   maintenance.
v1->v2:
 * Dropped patch#2 as it is accepted.
 * Moved patch#4 to patch#2.
 * Updated commit header and description for patch#2.
 * Kept RCANFD_CFG* macro definitions to give a meaning to the magic
   number using GENMASK macro and used FIELD_PREP to extract value.
 * Split patch#3 for computing nominal  and data bit rate config separate.
 * Updated rcar_canfd_compute_nominal_bit_rate_cfg() to handle
   nominal bit rate configuration for both classical CAN and CANFD.
 * Replaced RCANFD_NCFG_NBRP->RCANFD_NCFG_NBRP_MASK and used FIELD_PREP to
   extract value.
 * Replaced RCANFD_DCFG_DBRP->RCANFD_DCFG_DBRP_MASK and used FIELD_PREP to
   extract value.
