powerpc/cpm: Reintroduce global spi_pram struct (fixes build issue)

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.)
