iwlwifi: mvm: Add DC2DC_CONFIG_CMD (0x83) cmd & TLV
Add DC2DC_CONFIG_CMD (0x83) cmd.
Add IWL_UCODE_TLV_CAPA_DC2DC_CONFIG_SUPPORT tlv.
The command allows the driver get & set the DCDC's frequency tune.
(freq_tune is the divider that is used to calculate the actual DCDC's
clock rate)
The command always returns the current/updated frequency tune values of
the DCDC.
