mac80211: set mesh formation field properly

Cap max peerings at 63 in accordance with IEEE-2012 8.4.2.100.7.
Triggers a beacon regeneration every time the number of peerings changes.
Previously this would only happen if the "accepting peerings" bit changed.

wireless: make TU conversion macros available

A few places in the code (mac80211 and iwlmvm) use the same
TU_TO_JIFFIES() macro and could use TU_TO_EXP_TIME() that
mac80211 has. Make these available to everyone and use them.

ieee80211: fix vht cap definitions

VHT_CAP_BEAMFORMER_ANTENNAS cap is actually defined in the draft as
VHT_CAP_BEAMFORMEE_STS_MAX, and its size is 3 bits long.

VHT_CAP_SOUNDING_DIMENSIONS is also 3 bits long.

Fix the definitions and change the cap masking accordingly.
