[PATCH] ppc32: ppc_sys fixes for 8xx and 82xx

This patch fixes a numbers of issues regarding to that both 8xx and 82xx
began to use ppc_sys model:
	- Platform is now identified by default deviceless SOC, if no
BOARD_CHIP_NAME is specified in the bard-specific header. For the list
of supported names refer to (arch/ppc/syslib/) mpc8xx_sys.c and
mpc82xx_sys.c for 8xx and 82xx respectively.
	- Fixed a bug in identification by name - if the name was not found,
it returned -1 instead of default deviceless ppc_spec.
	- fixed devices amount in the 8xx platform system descriptions
