RZ/G2L has separate IRQ lines for tx and error interrupt for each channel whereas R-Car has a combined IRQ line for all the channel specific tx and error interrupts. Add multi_channel_irqs to struct rcar_canfd_hw_info to select the driver to choose between combined and separate irq registration for channel interrupts. This patch also removes enum rcanfd_chip_id and chip_id from both struct rcar_canfd_hw_info, as it is unused.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
