Enhance rt2x00 infrastructure by adding explicit information
about used chipset interface to struct rt2x00_chip.
The new field will be used by rt2800 drivers for rt2800 library.
Also add commonly used rt2x00_intf_is_pci() and rt2x00_intf_is_usb()
helpers to make code easier to read (noticed by Ivo van Doorn).

The calculated values for the ACK timeout and ACK
consume time are different then the values as
used by the Legacy drivers.
After testing from James Ledwith it appeared that
the calculated values caused a high amount of TX
failures, and the values from the Legacy drivers
were the most optimal to prevent TX failure due to
excessive retries.
The symptoms of this problem:
- Rate control module always falls back to 1Mbs
- Low throughput when bitrate was fixed
Possible side-effects (not confirmed but highly likely)
- Problems with DHCP
- Broken connections due to lack of probe response
This should fix at least:
Kernel bugzilla reports: [13362], [13009], [9273]
Fedora bugzilla reports: [443203]
but possible some additional bugs as well.

The old function rt2x00queue_payload_align() handled
both adding and removing L2 padding and some basic
frame alignment. The entire function was being abused
because it had multiple functions and the header length
argument was somtimes used to align the header instead
of the payload.
Additionally there was a bug when inserting L2 padding
that only the payload was aligned but not the header. This
happens when the header wasn't aligned properly by mac80211,
but rt2x00lib only moves the payload.
A secondary problem was that when removing L2 padding during
TXdone or RX the skb wasn't resized to the proper size.
Split the function into seperate functions each handling
its task as it should.
