arch: remove frv port
The Fujitsu FRV kernel port has been around for a long time, but has not seen regular updates in several years and instead was marked 'Orphaned' in 2016 by long-time maintainer David Howells. The SoC product line apparently is apparently still around in the form of the Socionext Milbeaut image processor, but this one no longer uses the FRV CPU cores. This removes all FRV specific files from the kernel. Link: http://www.socionext.com/en/products/assp/milbeaut/ Cc: David Howells <dhowells@redhat.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de>

-/* Core file format: The core file is written in such a way that gdb
- * can understand it and provide useful information to the user (under
- * linux we use the 'trad-core' bfd). There are quite a number of
- * obstacles to being able to view the contents of the floating point
- * registers, and until these are solved you will not be able to view
- * the contents of them. Actually, you can read in the core file and
- * look at the contents of the user struct to find out what the
- * floating point registers contain.
- *
- * The actual file contents are as follows:
- * UPAGE:
- * 1 page consisting of a user struct that tells gdb what is present
- * in the file. Directly after this is a copy of the task_struct,
- * which is currently not used by gdb, but it may come in useful at
- * some point. All of the registers are stored as part of the
- * upage. The upage should always be only one page.
- *
- * DATA:
- * The data area is stored. We use current->end_text to
- * current->brk to pick up all of the user variables, plus any
- * memory that may have been malloced. No attempt is made to
- * determine if a page is demand-zero or if a page is totally
- * unused, we just cover the entire range. All of the addresses are
- * rounded in such a way that an integral number of pages is
- * written.
- *
- * STACK:
- * We need the stack information in order to get a meaningful
- * backtrace. We need to write the data from (esp) to
- * current->start_stack, so we round each of these off in order to
- * be able to write an integer number of pages. The minimum core
- * file size is 3 pages, or 12288 bytes.

- * this will be used by gdb to figure out where the data and stack segments
- * are within the file, and what virtual addresses to use.
