can: bittiming: replace CAN units with the generic ones from linux/units.h

In [1], we introduced a set of units in linux/can/bittiming.h. Since
then, generic SI prefixes were added to linux/units.h in [2]. Those
new prefixes can perfectly replace CAN specific ones.

This patch replaces all occurrences of the CAN units with their
corresponding prefix (from linux/units) and the unit (as a comment)
according to below table.

CAN units SI metric prefix (from linux/units) + unit (as a comment)
------------------------------------------------------------------------
CAN_KBPS KILO /* BPS */
CAN_MBPS MEGA /* BPS */
CAM_MHZ MEGA /* Hz */

The definition are then removed from linux/can/bittiming.h

[1] commit 1d7750760b70 ("can: bittiming: add CAN_KBPS, CAN_MBPS and
CAN_MHZ macros")

[2] commit 26471d4a6cf8 ("units: Add SI metric prefix definitions")

can: etas_es58x: rewrite the message cast in es58{1,_fd}_tx_can_msg to increase readability

The es581_tx_can_msg() does below cast:
| tx_can_msg = (struct es581_4_tx_can_msg *)
| &es581_4_urb_cmd->bulk_tx_can_msg.tx_can_msg_buf[msg_len - 1];

The -1 offset is to skip the first member of struct
es581_4_tx_can_msg. However, es581_4_urb_cmd already has a raw_msg
field which can be used instead without the use of an offset
calculation.

The function es58x_fd_tx_can_msg() is also modified to mirror
es581_tx_can_msg().

can: etas_es58x: use sizeof and sizeof_field macros instead of constant values

Replace two constant values by a call to sizeof{,_field} on the
relevant field to make the logic easier to understand.
