MIPS: Remove asm/user.h

The struct user definition in this file is not used anywhere (the ELF
core dumper does not use that format). Therefore, remove the header and
instead enable the asm-generic user.h which is an empty header to
satisfy a few generic headers which still try to include user.h.

- * 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, NOT the irix-core).  The 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 handy at some point.  All of the registers
- *      are stored as part of the upage.  The upage should always be
- *      only one page long.
- *  data: The data segment follows next.  We use current->end_text to
- *      current->brk to pick up all of the user variables, plus any memory
- *      that may have been sbrk'ed.  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 usp to
- *      current->start_stack, so we round each of these in order to be able
- *      to write an integer number of pages.
