powerpc: Force cast on memcpy_toio()
sparse reports the following warning:
CHECK arch/powerpc/cpu/mpc8xx/micropatch_usb_sof.c
arch/powerpc/cpu/mpc8xx/micropatch_usb_sof.c:29:9: warning: cast removes address space '<asn:2>' of expression
arch/powerpc/cpu/mpc8xx/micropatch_usb_sof.c:30:9: warning: cast removes address space '<asn:2>' of expression
This is because of (void *) casts for using memcpy() as a substitute.
Do like other architectures, __force the cast to silence the warning
