wifi: iwlwifi: mvm: use a radio/system specific power budget

Different hardware has a different maximum power consumption and the
BIOS can also define a power limit for the device. Add code to select
an appropriate maximum power budget for the device and configure that
instead of using a hardcoded table.

This removes the old table. It does not work with the variable upper
limit and the there should be no consumer that requires these exact step
values.

This considerably increases the power budget for some devices and can
prevent throttling in high traffic situations.
