Subject: [PATCH 5/6] staging: r8188eu: DYNAMIC_RF_CALIBRATION is not used

Remove the DYNAMIC_RF_CALIBRATION capability. It's cleared in one place
but never checked.

DYNAMIC_RF_CALIBRATION is part of podmpriv->SupportAbility, there are no
users that check SupportAbility as a whole and use DYNAMIC_RF_CALIBRATION
implicitly.
