libkern: Add libcalls for ffs and __ffsdi2
These are needed when compiling a RISC-V kernel with GCC which does
not inline __builtin_ffs*.
The __ffsdi2 is adapated from the previous ffsl.c.
This partially reverts commit f4db342d44198973c1c7b9005d0c5683a582707e.

linux: Make the macro LINUX_IOCTL_SET public
There're some other drivers want to register and unregister linux
ioctl handler. Move the macro LINUX_IOCTL_SET from tdfx_linux.h to
linux_ioctl.h so that they can also benefit it.
While here, rename the declaration of linux ioctl function to be
consistent with the name of the handler.
Meanwhile, drop a comment about the macro, since its function is
obvious.
