[PATCH] Fix target architecture address size inside gdbarch structure

[Denis Dmitriev <zealot351@gmail.com>]

Hi all,
GDB can't get information about instructions when debugging mips:octeon2
architecture.
The problem is that the gdbarch structure contains the wrong address size
for target architecture (gdbarch->addr_bit, 32).
However, in the same structure there is data settings for the target
architecture (mips:octeon2) which indicate the correct address size
(gdbarch->bfd_arch_info->bits_per_address, 64).
This patch fixes creation gdbarch structure. Now the address size is taken
directly from the settings (gdbarch->bfd_arch_info).
