Added mutex lock for nvmem write/move operations. In the current implementation, there is no single entry point for the platform specific NvMem calls. The mutex lock is coupled with a task number so that the same task can attempt to grab the lock without stalling itself. In addition to the mutex lock, changed where the cache.base_ptr variable is updated. Previously, this was done prior to the partition being copied from flash to the shared memory area. Now, the variable is only updated after the copy so that read operations will always read from the correctly from either flash or from cache memory if a write operation has been started. BRANCH=none BUG=chrome-os-partner:52520 TEST=Manual make runtests TEST_LIST_HOST=nvmem and verify that all tests pass. Tested with tcg_test utility to test reads/writes using the command "build/test-tpm2/install/bin/compliance --ntpm localhost:9883 --select CPCTPM_TC2_3_33_07_01".
