iwlwifi: fix TX cmd dma unmapping
This patch:
1. fixes command DMA unmapping, this might be visible only
on platforms where DMA unmapping is no noop such as PPC64 (not tested)
2. attaches correctly high memory part of the host command buffer
3. changes structure of TFD TB
instead of describing transmit buffer (TB) tuple it describes single
TB and makes code more readable on price of one unaligned access
4. eliminates using of IWL_GET/SET_BITs for TFD handling
5. renames TFD structures to mach the HW spec
6. reduces iwl_tx_info size by reserving first TB to the host command
This patch should not have any visible effect on x86 32
This patch is rework of
iwlwifi: fix DMA code and bugs from
