Subject: [PATCH] hostapd: Update EHT capabilities IE as per draft 3.0

Update EHT capabilities IE definitions as per 11be draft 3.0
specification.

Add the below EHT capabilities IE definitions,
EHT MAC Capabilities(Draft 3.1 - 9.4.2.313.2):
Two BQRs Support - B11(1 Bit)
EHT Link Adaptation Support - B12,B13(2 Bits)

EHT PHY Capabilities(Draft 3.1 - 9.4.2.313.3):
20 MHz-Only Limited Capabilities Support - B66(1 Bit)
20 MHz-Only Triggered MU Beamforming Full BW Feedback And
DL MU-MIMO - B67(1 Bit)
20 MHz-Only M-RU Support - B68(1 Bit)
