The individual sensor drivers implemented in the ISH firmware needs
capability to take special actions when there is a change in the system
standby state. The ISH core firmware passes this notification to
individual sensor drivers in response to the OS request via connected
standby bit in the SYSTEM_STATE_STATUS command.
This change sets CONNECTED_STANDBY_STATE_BIT bit to 1 during suspend
callback and clears during resume callback.

Instead of using an 128-byte on-stack array to store the request, we can
instantiate the request on stack directly. This can save the stack usage of
these functions, since most of the requests are much smaller than 128 bytes.

Variable num_frags is being assigned but is never used hence it is
redundant and can be removed.
Cleans up clang warning:
warning: variable 'num_frags' set but not used [-Wunused-but-set-variable]

The internal accounting uses 'timespec' based time stamps, which is
slightly inefficient and also problematic once we get to the time_t
overflow in 2038.
When communicating to the firmware, we even get an open-coded 64-bit
division that prevents the code from being build-tested on 32-bit
architectures and is inefficient due to the double conversion from
64-bit nanoseconds to seconds+nanoseconds and then microseconds.
This changes the code to use ktime_t instead.

Although unlikely but it is possible that when a connect or disconnect
request is issued to the firmware, before the response comes, user
terminates the client session. In this case when the response is arrived
there is no matching client instance in the list of currently active
clients. In this case, don't issue call to wake up a waiting client.

The ISH transport layer (ishtp) is a bi-directional protocol implemented
on the top of PCI based inter processor communication layer. This layer
offers:
- Connection management
- Flow control with the firmware
- Multiple client sessions
- Client message transfer
- Client message reception
- DMA for RX and TX for fast data transfer
Refer to Documentation/hid/intel-ish-hid.txt for
overview of the functionality implemented in this layer.
