wifi: iwlwifi: remove unused header inclusions

Remove header files that are included but provide no symbols,
types, or macros used by the including translation unit.

In iwl-trans.c, fw/api/tx.h defines TX command structures
(iwl_tx_cmd, iwl_tx_resp, TX_CMD_* flags) used by the PCIe TX
path, not by the transport core itself. Similarly, iwl-fh.h
defines Flow Handler register addresses and DMA-related constants
(FH_*, RFH_*, TFD_*) that are consumed by PCIe-specific code,
none of which are referenced in iwl-trans.c.

In iwl-nvm-parse.c, fw/acpi.h defines ACPI/SAR/GEO/PPAG
interfaces (iwl_acpi_*, iwl_sar_*, iwl_geo_*). No references to
any of these interfaces exist in this file.
