Subject: [PATCH] riscv: remove redundant kernel-space generic-y

This commit removes redundant generic-y defines in
arch/riscv/include/asm/Kbuild.

[1] It is redundant to define the same generic-y in both
    arch/$(ARCH)/include/asm/Kbuild and
    arch/$(ARCH)/include/uapi/asm/Kbuild.

    Remove the following generic-y:

      errno.h
      fcntl.h
      ioctl.h
      ioctls.h
      ipcbuf.h
      mman.h
      msgbuf.h
      param.h
      poll.h
      posix_types.h
      resource.h
      sembuf.h
      setup.h
      shmbuf.h
      signal.h
      socket.h
      sockios.h
      stat.h
      statfs.h
      swab.h
      termbits.h
      termios.h
      types.h

[2] It is redundant to define generic-y when arch-specific
    implementation exists in arch/$(ARCH)/include/asm/*.h

    Remove the following generic-y:

      cacheflush.h
      dma-mapping.h
      module.h
