8f445a3ec3 can: ctucanfd: platform: add missing dependency to HAS_IOMEM 
The kernel test robot noticed that the ctucanfd platform driver fails
during modpost on platforms that don't support IOMEM.

| ERROR: modpost: "devm_ioremap_resource" [drivers/net/can/ctucanfd/ctucanfd_platform.ko] undefined!

This patch adds the missing HAS_IOMEM dependency.

6c1e423a3c can: can-dev: remove obsolete CAN LED support 
Since commit 30f3b42147 ("can: mark led trigger as broken") the
CAN specific LED support was disabled and marked as BROKEN. As the
common LED support with CONFIG_LEDS_TRIGGER_NETDEV should do this work
now the code can be removed as preparation for a CAN netdevice Kconfig
rework.

94737ef56b can: ctucanfd: Let users select instead of depend on CAN_CTUCANFD 
The CTU CAN-FD IP core is only useful when used with one of the
corresponding PCI/PCIe or platform (FPGA, SoC) drivers, which depend on
PCI resp. OF.

Hence make the users select the core driver code, instead of letting
then depend on it.  Keep the core code config option visible when
compile-testing, to maintain compile-coverage.
