handling function must be accustomized.

The loop is mandatory when edge triggered interrupts are used.
It is necessary to achieve state when all enabled interrupts are
served and cleared or disabled and actual IRQ pin or MSI
request is inactive.

Some more cleanup to access chip only through routines
and register description found in ctu_can_fd_hw.h
and ctu_can_fd_regs.h.

Register map was renamed in IP-XACT, thus the re-generation.
Maybe a little long, but it looks better in IP-XACT. Otherwise
mem map name was just "Regs" which was not what one was seeing
in documentation...

- linux module
- use priv->{read,write}_reg instead of direct calls
- add ctu_can_fd_reset
- number buffers from 0, not from 1
- fix: ctu_can_fd_set_mode: oneshot, berr_reporting
- ctu_can_fd_read_err_ctrs: requires non-null params
- ctu_can_fd_read_rx_frame: option to fetch the first ID word sooner
  to determine FD/non-FD frame for skb allocation
- ctu_can_fd_insert_frame: add param isfd, fix for RTR
- minor optimizations

TODO: split this large commit

Not yet final! Interrupt macros are still remaining.
