tpm_tis_remove() leads to calling tpm_tis_ready() with the IO region
unmapped and chip->locality == -1 (locality released). This leads to a
crash in mmio_write_bytes().
The patch implements these changes:
tpm_tis_remove(): Unmap the IO region after calling tpm_tis_cleanup().
tpm_tis_cleanup(): Request locality before IO output and releasing
locality.

efi_loader: Extend PCR's for firmware measurements
Firmwares before U-Boot may be capable of doing tpm measurements
and passing them to U-Boot in the form of eventlog. However there
may be scenarios where the firmwares don't have TPM driver and
are not capable of extending the measurements in the PCRs.
Based on TCG spec, if previous firnware has extended PCR's, PCR0
would not be 0. So, read the PCR0 to determine if the PCR's need
to be extended as eventlog is parsed or not.

tpm: use more algorithms than sha256 on pcr_read
The current tpm2_pcr_read is hardcoded using SHA256. Make the
actual command to TPM configurable to use wider range of algorithms.
The current command line is kept as is i.e limited to SHA-256 only.

efi_loader: Add check for event log passed from firmware
Platforms may have support to measure their initial firmware components
and pass the event log to u-boot. The event log address can be passed
in property tpm_event_log_addr and tpm_event_log_size of the tpm node.
Platforms may choose their own specific mechanism to do so. A weak
function is added to check if even log has been passed to u-boot
from earlier firmware components. If available, the eventlog is parsed
to check for its correctness and further event logs are appended to the
passed log.
