optimize read_tpm_nvmem()
This patch optimizes read_tpm_nvmem() by replacing NvGetIndexData()
and NvGetIndexInfo() with NvReadIndexDta() and NvReadIndexInfo()
respectively.
This will reduce NvFindHandle() calls from three to one.
BUG=b:148489182
BRANCH=cr50, cr50-mp
TEST=The function execution time reduces from 1.2 msec to 550 usec.
