[POWERPC] Fix mv643xx_pci sysfs .read and .write functions

Commit 91a69029 introduced an additional parameter to the .read and .write
methods for sysfs binary attributes.  Two mv64x60_pci functions
were missed in that patch, resulting in these errors:
	/cache/git/linux-2.6/arch/powerpc/sysdev/mv64x60_pci.c:77: warning: initialization from incompatible pointer type
	/cache/git/linux-2.6/arch/powerpc/sysdev/mv64x60_pci.c:78: warning: initialization from incompatible pointer type

Add the missing "struct bin_attribute *" parameter.
