Add new QCA vendor attribute to set thermal level

Browse source 
Add a new QCA vendor attribute to set thermal level to the driver from
userspace. The driver/firmware takes actions requested by userspace to
mitigate high temperature such as throttling TX etc. The driver may
choose the level of throttling and other actions for various thermal
levels set by userspace.
