tpm: tpm_ibm_vtpm: Fix unallocated banks
The nr_allocated_banks and allocated banks are initialized as part of tpm_chip_register. Currently, this is done as part of auto startup function. However, some drivers, like the ibm vtpm driver, do not run auto startup during initialization. This results in uninitialized memory issue and causes a kernel panic during boot. This patch moves the pcr allocation outside the auto startup function into tpm_chip_register. This ensures that allocated banks are initialized in any case.
