Arnd Bergmann f16394792f cpuidle: add ARCH_SUSPEND_POSSIBLE dependencies 
commit 7787943a3a upstream.

Some ARMv4 processors don't support suspend, which leads
to a build failure with the tegra and qualcomm cpuidle driver:

WARNING: unmet direct dependencies detected for ARM_CPU_SUSPEND
  Depends on [n]: ARCH_SUSPEND_POSSIBLE [=n]
  Selected by [y]:
  - ARM_TEGRA_CPUIDLE [=y] && CPU_IDLE [=y] && (ARM [=y] || ARM64) && (ARCH_TEGRA [=n] || COMPILE_TEST [=y]) && !ARM64 && MMU [=y]

arch/arm/kernel/sleep.o: in function `__cpu_suspend':
(.text+0x68): undefined reference to `cpu_sa110_suspend_size'
(.text+0x68): undefined reference to `cpu_fa526_suspend_size'

Add an explicit dependency to make randconfig builds avoid
this combination.

Fixes: faae6c9f2e ("cpuidle: tegra: Enable compile testing")
Fixes: a871be6b8e ("cpuidle: Convert Qualcomm SPM driver to a generic CPUidle driver")

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
