  target/xtensa: gdbstub fix register counting

In order to communicate correctly with gdb xtensa gdbstub must provide
expected number of registers in 'g' packet response. xtensa-elf-gdb
expects both nonprivileged and privileged registers. xtensa-linux-gdb
only expects nonprivileged registers. gdb only counts one contiguous
stretch of registers, do the same for the core registers in the
xtensa_count_regs.

With this change qemu-system-xtensa is able to communicate with all
xtensa-elf-gdb versions (versions prior to 8.2 require overlay fixup),
and qemu-xtensa is able to communicate with all xtensa-linux-gdb
versions, except 8.2.

  target/xtensa: drop num_[core_]regs from dc232b/dc233c configs

Now that xtensa_count_regs does the right thing, remove manual
initialization of these fields from the affected configurations and let
xtensa_finalize_config initialize them. Add XTREG_END to terminate
register lists.

  target/xtensa: xtfpga: provide default memory sizes

Provide default RAM sizes for all XTFPGA boards, so that when started
without -m option they do the right thing.
