If CONFIG_NET is not defined then THERMAL_NETLINK can't be selected.

Hence add dependency on CONFIG_NET. Othewise it will generate compile
errors while compiling thermal_netlink.c.

Currently some user space programs like Linux thermald needs to register
to get notifications from both thermal user space governor and also
Thermal netlink. This is required as some messages like HFI (Hardware
Feedback Notifications) requires Thermal netlink.

This results in additional processing in kernel and user space to process
both notifications. The cost of using user space governor using
kobject_uevent is much higher as this is also used by other user space
daemons like udev daemon.

Do not select user_space thermal governor by default. If it is present
user space programs can always use this governor by writing to
"policy" attribute.

Instead from the kernel select THERMAL_NETLINK. Trip temperature
violation can be received by user space programs via thermal netlink
events:
THERMAL_GENL_EVENT_TZ_TRIP_UP
THERMAL_GENL_EVENT_TZ_TRIP_DOWN

Clean up the existing export namespace code along the same lines of
commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo)
to __section("foo")") and for the same reason, it is not desired for the
namespace argument to be a macro expansion itself.

The group only contains a single entry and the conditionals around its
lifecycle make clear that this won't change.

Remove the unnecessary group.

This saves some memory and it's easier to read.

The removal of a non-const bin_attribute[] instance is also a
preparation for the constification of struct bin_attributes.

When the current_uuid attribute is set to the active policy UUID,
reading back the same attribute is returning "INVALID" instead of
the active policy UUID on some platforms before Ice Lake.

In platforms before Ice Lake, firmware provides a list of supported
thermal policies. In this case, user space can select any of the
supported thermal policies via a write to attribute "current_uuid".

In commit c7ff29763989 ("thermal: int340x: Update OS policy capability
handshake")', the OS policy handshake was updated to support Ice Lake
and later platforms and it treated priv->current_uuid_index=0 as
invalid. However, priv->current_uuid_index=0 is for the active policy,
only priv->current_uuid_index=-1 is invalid.

Fix this issue by updating the priv->current_uuid_index check.
