Guo Ren abbb887da7 riscv: Fixup compile error with !MMU 
commit c528ef0888 upstream.

Current nommu_virt_defconfig can't compile:

In file included from
arch/riscv/kernel/crash_core.c:3:
arch/riscv/kernel/crash_core.c:
In function 'arch_crash_save_vmcoreinfo':
arch/riscv/kernel/crash_core.c:8:27:
error: 'VA_BITS' undeclared (first use in this function)
    8 |         VMCOREINFO_NUMBER(VA_BITS);
      |                           ^~~~~~~

Add MMU dependency for KEXEC_FILE.

Fixes: 6261586e0c ("RISC-V: Add kexec_file support")

README 

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.
