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.

<title>thermal: int3400: Fix reading of current_uuid for active policy</title>

<id>7082503622986537f57bdb5ef23e69e70cfad881</id>
<content type='text'>
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-&gt;current_uuid_index=0 as
invalid. However, priv-&gt;current_uuid_index=0 is for the active policy,
only priv-&gt;current_uuid_index=-1 is invalid.

Fix this issue by updating the priv-&gt;current_uuid_index check.

<content type='text'>
After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/thermal to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

On the way make a few whitespace changes to make indention consistent.

<content type='text'>
Similar to the MSR RAPL interface, MMIO RAPL supports PL4 too, so add
MMIO RAPL PL4d support to the processor_thermal driver.

As a result, the powercap sysfs for MMIO RAPL will show a new "peak
power" constraint.

CPU0/package0 is always online and the MMIO RAPL driver runs on single
package systems only, so there is no need to handle CPU hotplug in it.

Always register a RAPL package device for package 0 and remove the
unnecessary CPU hotplug support.

The processor_thermal driver uses pcim_device_enable() to enable a PCI
device, which means the device will be automatically disabled on driver
detach.  Thus there is no need to call pci_disable_device() again on it.

With recent PCI device resource management improvements, e.g. commit
f748a07a0b64 ("PCI: Remove legacy pcim_release()"), this problem is
exposed and triggers the warining below.
