Input: Allow compile test of Goodix and Colibri VF50 if !GPIOLIB
The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is
not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer
functionality only, can still be compiled if GPIOLIB is not enabled.
If COMPILE_TEST is enabled, relax the dependency on GPIOLIB for the
recently introduced or relaxed symbols TOUCHSCREEN_GOODIX and
TOUCHSCREEN_COLIBRI_VF50.

thermal: allow u8500-thermal driver to be a module
When the thermal subsystem is a loadable module, the u8500 driver
fails to build:
drivers/thermal/built-in.o: In function `db8500_thermal_probe':
db8500_thermal.c:(.text+0x96c): undefined reference to `thermal_zone_device_register'
drivers/thermal/built-in.o: In function `db8500_thermal_work':
db8500_thermal.c:(.text+0xab4): undefined reference to `thermal_zone_device_update'
This changes the symbol to a tristate, so Kconfig can track the
dependency correctly.

thermal: spear: use __maybe_unused for PM functions
The spear thermal driver hides its suspend/resume function conditionally
based on CONFIG_PM, but references them based on CONFIG_PM_SLEEP, so
we get a warning if the former is set but the latter is not:
thermal/spear_thermal.c:58:12: warning: 'spear_thermal_suspend' defined but not used [-Wunused-function]
thermal/spear_thermal.c:75:12: warning: 'spear_thermal_resume' defined but not used [-Wunused-function]
This removes the #ifdef and instead uses a __maybe_uninitialized
annotation to avoid the warning and improve compile-time coverage.
This patch enables to use thermal-zone on DT if it was calles as
"renesas,rcar-thermal-gen2".
Previous style (= non thermal-zone) is still supported by
"renesas,rcar-thermal" to keep compatibility for "git bisect".

cpufreq: governor: Symmetrize cpu_dbs_info initialization and cleanup
Make the initialization of struct cpu_dbs_info objects in
alloc_policy_dbs_info() and the code that cleans them up in
free_policy_dbs_info() more symmetrical. In particular,
set/clear the update_util.func field in those functions along
with the policy_dbs field.

cpufreq: governor: Rearrange governor data structures
The struct policy_dbs_info objects representing per-policy governor
data are not accessible directly from the corresponding policy
objects. To access them, one has to get a pointer to the
struct cpu_dbs_info of policy->cpu and use the policy_dbs field of
that which isn't really straightforward.
To address that rearrange the governor data structures so the
governor_data pointer in struct cpufreq_policy will point to
struct policy_dbs_info (instead of struct dbs_data) and that will
contain a pointer to struct dbs_data.

Use the observation that cpufreq_governor_limits() doesn't have to
get to the policy object it wants to manipulate by walking the
reference chain cdbs->policy_dbs->policy, as the final pointer is
actually equal to its argument, and make it access the policy
object directy via its argument.
