powerpc/kvm: Fix the build for 32-bit Book 3S (classic) processors

Commits a5d4f3a ("powerpc: Base support for exceptions using HSRR0/1") and 673b189 ("powerpc: Always use SPRN_SPRG_HSCRATCH0 when running in HV mode") cause compile and link errors for 32-bit classic Book 3S processors when KVM is enabled. This fixes these errors. Signed-off-by: Paul Mackerras <[email protected]> Signed-off-by: Benjamin Herrenschmidt <[email protected]>
