[U-Boot] commit a37c36f4 breaks several non-85xx boards

Dear Kim,

your commit a37c36f4: "powerpc/8xxx: query feature reporting register for num cores on unknown cpus" breaks a number of boards with error messages like here:

cpu.c: In function 'cpu_numcores': cpu.c:113: error: 'CONFIG_SYS_MPC85xx_PIC_ADDR' undeclared (first use in this function) cpu.c:113: error: (Each undeclared identifier is reported only once cpu.c:113: error: for each function it appears in.) cpu.c:118: error: 'MPC85xx_PICFRR_NCPU_MASK' undeclared (first use in this function) cpu.c:119: error: 'MPC85xx_PICFRR_NCPU_SHIFT' undeclared (first use in this function) make[1]: *** [/work/wd/tmp-ppc/arch/powerpc/cpu/mpc8xxx/cpu.o] Error 1 make: *** [/work/wd/tmp-ppc/arch/powerpc/cpu/mpc8xxx/lib8xxx.a] Error 2

Affected board configurations: MPC8610HPCD, MPC8641HPCN, MPC8641HPCN_36BIT, XPEDITE5170, sbc8641d.

Please fix.

Thanks in advance.

Best regards,
