  1. plat-ti: Rename platform context to platform boot arguments 

    Currently the non-secure context is passed in from our initial secure
software as part of the OP-TEE load process. This passed-in data will
not only contain the non-secure context but also any additional data we
may need to give to OP-TEE. Rename these structures and group the context
data into a struct for future expansion.

  2. plat-ti: Read and store HUK sent by initial secure software 

    Some TI platforms pass the HUK to OP-TEE via a secure memory stack. Read
and store this key for later use. On platforms without CFG_OTP_SUPPORT
this key is ignored.

  3. plat-ti: Add support for using HUK on DRA7xx/AM57xx 

    On DRA7xx/AM57xx the initial secure software will pass OP-TEE a
Hardware Unique Key (HUK), use this key when requested.
