PROVISORY: ci: cram: freedom: workaround rad2g bw 40MHz cold setting failure

Browse Source 
Problem:
- cold applying rad2g bw 40MHz in cram script
106-pwhm-get-eht-caps_step_1.t is leading to systematic failure

Cause:
- overriding BSS coexistence is detected in the testing environnement,
leading to falling back to bw 20mhz in rad2g
- but the script is expecting 40mhz
- pwhm is re-applying the bw which keeps reduced

Workaround:
- set rad2g bw 20MHz in the initial cold apply setting
- set rad2g bw 40MHz later in warm apply setting (through CSA, not impacting
the hostapd initial setup)
- set back rad2g to bw 20MHz when setting 11ax

Expected fix:
- in pwhm: prevent forcing 40MHz when it was reduced to 20MHz by
hostapd/driver due to OBSS_COEX reason
- improve the cram script to consider current bw as applied by the
driver
