spmi: pmic-arb: Always allocate ppid_to_apid table
After commit7f1d4e58da
("spmi: pmic-arb: optimize table lookups") we always need the ppid_to_apid table regardless of the version of pmic arbiter we have. Otherwise, we will try to deref the array when we don't allocate it on v2 hardware like the msm8974 SoCs.
