MIPS: Go back with the default Linux # of registers to 90
Set the number of registers for non-XML-described Linux targets to 90,
reverting a change made here with the addition of DSP register support:
commit 1faeff088bbbd037d7769d214378b4faf805fa2e

and fixing a regression introduced for legacy `gdbserver' targets
causing a "Remote 'g' packet reply is too long" error message where the
amount of register data received with a `g' packet (90) exceeds the
maximum number of registers expected (79).
Update the setting for XML-described targets, reflecting the actual
number of registers which have been assigned numbers, matching the:
gdb_assert (gdbarch_num_regs (gdbarch) <= MIPS_RESTART_REGNUM);
requirement in `mips_linux_init_abi'.
gdb/
* mips-tdep.c (mips_gdbarch_init): For GDB_OSABI_LINUX set
`num_regs' to 90 rather than 79. Where a target description is
present adjust the setting appropriately.
