e29851c910 PFK: fix race between key set and key invalidate in TZ
When working with multiple files and multiple threads, the following
scenario can occur:
1. File Close -> Key cache removal -> context switch
2. Open new file -> occupy the entry cleaned in 1
   -> TZ_ES_SET_ICE_KEY -> context switch
3. Back to 1 -> TZ_ES_INVALIDATE_ICE_KEY
4. Back to 2 -> ICE uses the key that is already invalid
5. Crash due to PARTIALLY_SET_KEY_USED

To fix this, pfk must know when requests using some key are completed.
Only then key removal shall be allowed and until then key invalidation
must wait.
A new callback was added to let clients inform PFK when requests end.

8928f8683b PFK: fixed issue where key in TZ was not set properly
When key is set in ICE via TZ, HLOS should send two parts, SALT and
the KEY itself according to AES standards. KEY was used for both parts.

584531e72e PFK: new module to work with ecryptfs
PFK is a new module that accompanies eCryptfs and
enables it to utilize ICE hw encryption engine. Module
is responsible for storing encryption/decryption keys
inside eCryptfs inodes for each file and loading them
to ICE
