ACPI: CPPC: initialise vaddr pointers to NULL
Properly initialise vaddr pointers in cpc_read() and cpc_write() to
NULL instead of 0.
This fixes the following sparse warnings:
drivers/acpi/cppc_acpi.c:937:31: warning: Using plain integer as NULL pointer
drivers/acpi/cppc_acpi.c:982:31: warning: Using plain integer as NULL pointer
