In preparation for cleaning up a number of files add
declarations for irq and smp related data/functions to
the relevant headers.
This showed that the extern declaration of cputypval differed
in the two files where it was used.
As cputypval is defined like this:
cputypval:
.asciz "sun4c"
the correct representation is a char array.
Fix users to use the new declaration.
