platform/x86: asus-wmi: don't fail if platform_profile already registered
On some newer laptops ASUS laptops SPS support is advertised but not
actually used, causing the AMD driver to register as a platform_profile
handler.
If this happens then the asus_wmi driver would error with -EEXIST when
trying to register its own handler leaving the user with a possibly
unusable system. This is especially true for laptops with an MCU that emit
a stream of HID packets, some of which can be misinterpreted as shutdown
signals.
We can safely continue loading the driver instead of bombing out.
