This is the third iteration of this PATCH series (not counting RFCs).
It addresses comments from Bartlomiej - thanks, Bartlomiej!

The first patch makes all the drivers store their mode in struct
thermal_zone_device. Such a move has consequences: driver-specific
variables for storing mode are not necessary. Consequently get_mode()
methods become obsolete. Then sysfs "mode" attribute stops depending
on get_mode() being provided, because it is always provided from now on.

The first patch also introduces the initial mode to be optionally passed
to thermal_zone_device_register().

Given all the groundwork done in patch 1/2 patch 2/2 becomes very simple.

I incorrectly named PATCH v2 a PATCH RESEND 1/2, so now I'm counting that
as PATCH v2, hence this series is PATCH v3.

PATCH v2..PATCH v3:
- removed redundant regmap_write() in imx_thermal_suspend() and
imx_thermal_resume() (Bartlomiej)
- removed unnecessary call to soc_dts_enable() (now called indirectly
from thermal_zone_device_register()->set_mode()) (Bartlomiej)
- removed defensive-style checks for non-existent enum values in
thermal_zone_device_set_mode() (Bartlomiej)
- change mode only if driver's set_mode() succeeded in
thermal_zone_device_set_mode() (Bartlomiej)
- don't set tz->need_update in thermal_zone_device_register() - this
was supposed to be part of PATCH v1, but was omitted (Bartlomiej)

PATCH..PATCH v2:

- fixed typo (missing semicolon in dummy thermal_zone_device_set_mode()
implementation) (kbuild test robot)
- fixed misspelled enum value in int3400_thermal_params.initial_mode

RFCv3..this PATCH:

- export thermal_zone_device_{enable|disable}() for drivers (Bartlomiej)
- don't check provided enum values in acpi's thermal_zet_mode()
and in int3400_thermal_set_mode() (Bartlomiej)
- use thermal_zone_device_enable() in of_thermal instead of open coding it
(Bartlomiej)
- use thermal_zone_device_{enable|disable}() in hisi_thermal, rockchip_thermal
and sprd_thermal (Bartlomiej)
- assume THERMAL_DEVICE_ENABLED is thermal_zone_params not provided at
tzd's register time (Bartlomiej)
- eliminated tzp-s which contain only .initial_mode = THERMAL_DEVICE_ENABLED,
(Bartlomiej)
- don't set tz->need_update and don't call thermal_zone_device_update()
at the end of thermal_zone_device_register() (Bartlomiej)
- used .initial_mode in int340x_thermal_zone, x86_pkg_temp_thermal and
int3400_thermal (Bartlomiej)
