Access through the GGTT (iomap) into the vma does require the device to
be awake. However, we often take the i915_vma_pin_iomap() as an early
preparatory step that is long before we use the iomap. Asserting that
the device is awake at pin time does not protect us, and is merely a
nuisance.

The EDIMM STARTER KIT i.Core 1.5 MIPI Evaluation is based on
the 1.5 version of the i.Core MX6 cpu module. The 1.5 version
differs from the original one for a few details, including the
ethernet PHY interface clock provider.
With this commit, the ethernet interface works properly:
SMSC LAN8710/LAN8720 2188000.ethernet-1:00: attached PHY driver
While before using the 1.5 version, ethernet failed to startup
do to un-clocked PHY interface:
fec 2188000.ethernet eth0: could not attach to PHY
Similar fix has merged for i.Core MX6Q but missed to update for DL.

Currently, "cipher" (single-block cipher) spawns are usually initialized
by using crypto_get_attr_alg() to look up the algorithm, then calling
crypto_init_spawn(). In one case, crypto_grab_spawn() is used directly.
The former way is different from how skcipher, aead, and akcipher spawns
are initialized (they use crypto_grab_*()), and for no good reason.
This difference introduces unnecessary complexity.
The crypto_grab_*() functions used to have some problems, like not
holding a reference to the algorithm and requiring the caller to
initialize spawn->base.inst. But those problems are fixed now.
Also, the cipher spawns are not strongly typed; e.g., the API requires
that the user manually specify the flags CRYPTO_ALG_TYPE_CIPHER and
CRYPTO_ALG_TYPE_MASK. Though the "cipher" algorithm type itself isn't
yet strongly typed, we can start by making the spawns strongly typed.
So, let's introduce a new 'struct crypto_cipher_spawn', and functions
crypto_grab_cipher() and crypto_drop_cipher() to grab and drop them.
Later patches will convert all cipher spawns to use these, then make
crypto_spawn_cipher() take 'struct crypto_cipher_spawn' as well, instead
of a bare 'struct crypto_spawn' as it currently does.
