powerpc/cpm1: Fix build with various CONFIG_*_UCODE_PATCH combinations

Warnings are treated as errors for arch/powerpc code, so build fails
with CONFIG_I2C_SPI_UCODE_PATCH=y:

    CC      arch/powerpc/sysdev/micropatch.o
  cc1: warnings being treated as errors
  arch/powerpc/sysdev/micropatch.c: In function 'cpm_load_patch':
  arch/powerpc/sysdev/micropatch.c:630: warning: unused variable 'smp'
  make[1]: *** [arch/powerpc/sysdev/micropatch.o] Error 1

And with CONFIG_USB_SOF_UCODE_PATCH=y:

  CC      arch/powerpc/sysdev/micropatch.o
  cc1: warnings being treated as errors
  arch/powerpc/sysdev/micropatch.c: In function 'cpm_load_patch':
  arch/powerpc/sysdev/micropatch.c:629: warning: unused variable 'spp'
  arch/powerpc/sysdev/micropatch.c:628: warning: unused variable 'iip'
  make[1]: *** [arch/powerpc/sysdev/micropatch.o] Error 1

This patch fixes these issues by introducing proper #ifdefs.
