This saves runtime memory and fixes lots of sparse warnings like this:
CHECK arch/powerpc/sysdev/micropatch.c
arch/powerpc/sysdev/micropatch.c:27:6: warning: symbol 'patch_2000'
was not declared. Should it be static?
arch/powerpc/sysdev/micropatch.c:146:6: warning: symbol 'patch_2f00'
was not declared. Should it be static?

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.

spi_t was removed in commit 644b2a680ccc51a9ec4d6beb12e9d47d2dee98e2
("powerpc/cpm: Remove SPI defines and spi structs"), the commit assumed
that spi_t isn't used anywhere outside of the spi_mpc8xxx driver. But
it appears that the struct is needed for micropatch code. So, let's
reintroduce the struct.
Fixes the following build issue:
CC arch/powerpc/sysdev/micropatch.o
micropatch.c: In function 'cpm_load_patch':
micropatch.c:629: error: expected '=', ',', ';', 'asm' or '__attribute__' before '*' token
micropatch.c:629: error: 'spp' undeclared (first use in this function)
micropatch.c:629: error: (Each undeclared identifier is reported only once
micropatch.c:629: error: for each function it appears in.)

Rename commproc.[ch] to cpm1.[ch] to be more consistent with cpm2. Also
rename cpm2_common.c to cpm2.c as suggested by Scott Wood. Adjust the
includes accordingly.

This covers common CPM access functions, CPM interrupt controller code,
micropatch and a few compatibility things to kee the same driver base
working with arch/ppc. This version is refined with all the comments
(mostly PIC-related) addressed.
