wifi: iwlwifi: validate PPAG table when sent to FW

We used to check enablement/validity of the PPAG table while reading
it from BIOS.
For newer FWs this checks were offloaded, and the driver needs
to send the PPAG table anyway.
The desicion whether the table needs to be validated before sending it
is FW related and shouln't be in 'read-from-bios' flow.
Move it to 'send-to-fw' flow instead.
This will also help to avoid code duplication of checking validity in
both ACPI and UEFI caes.
