SPM driver provides cpuidle support on some QC SoC's. The functionality
is non-modular and there is no need for module support. Convert module
platform init to builtin platform driver init. The driver functionality
is not affected by this change.

gcc warns about the 'found' variable possibly being used uninitialized:
drivers/soc/qcom/spm.c: In function 'spm_dev_probe':
drivers/soc/qcom/spm.c:305:5: error: 'found' may be used uninitialized in this function [-Werror=maybe-uninitialized]
However, the code is correct because we know that there is
always at least one online CPU. This initializes the 'found'
variable to zero before the loop so the compiler knows
it does not have to warn about it.

The suspend() hook in the cpuidle_ops struct is always called on
the cpu entering idle, which means that the cpu parameter passed
to the suspend hook always corresponds to the local cpu, making
it somewhat redundant.
This patch removes the logical cpu parameter from the ARM
cpuidle_ops.suspend hook and updates all the existing kernel
implementations to reflect this change.

The ifc6410 firmware always enters the kernel in ARM state from
deep idle. Use the cpu_resume_arm() wrapper instead of
cpu_resume() to property switch into the THUMB2 state when we
wake up from idle.
This fixes a problem reported by Kevin Hilman on next-20150601
where the ifc6410 fails to boot a THUMB2 kernel because the
platform's firmware always enters the kernel in ARM mode from
deep idle states.

SPM is a hardware block that controls the peripheral logic surrounding
the application cores (cpu/l$). When the core executes WFI instruction,
the SPM takes over the putting the core in low power state as
configured. The wake up for the SPM is an interrupt at the GIC, which
then completes the rest of low power mode sequence and brings the core
out of low power mode.
The SPM has a set of control registers that configure the SPMs
individually based on the type of the core and the runtime conditions.
SPM is a finite state machine block to which a sequence is provided and
it interprets the bytes and executes them in sequence. Each low power
mode that the core can enter into is provided to the SPM as a sequence.
Configure the SPM to set the core (cpu or L2) into its low power mode,
the index of the first command in the sequence is set in the SPM_CTL
register. When the core executes ARM wfi instruction, it triggers the
SPM state machine to start executing from that index. The SPM state
machine waits until the interrupt occurs and starts executing the rest
of the sequence until it hits the end of the sequence. The end of the
sequence jumps the core out of its low power mode.
Add support for an idle driver to set up the SPM to place the core in
Standby or Standalone power collapse mode when the core is idle.
