cd7ae54934 iwlwifi: mvm: fix old-style static const declaration 
GCC reports warning as follows:

   14 | const static struct iwl_rfi_lut_entry iwl_rfi_table[IWL_RFI_LUT_SIZE] = {

Move static to the beginning of declaration.

21254908cb iwlwifi: mvm: add RFI-M support 
RF Interference Mitigation is a new feature targeted to handle the
problem of interference between DDR memory and WiFi. The role of
the driver is to configure FW with the table holding a mapping
between problematic channels/bands and the corresponding frequencies.

This patch adds RFI infrastructure and adds two debugfs hooks:
- send RFI configuration command (currently with a default table) which
  will reset feature in the FW
- read the table, used by the FW (which can be a subset of the table
  that driver sent).
