Zong-Zhe Yang 14a5b11532 wifi: rtw88: 8821c: tweak CCK TX filter setting for SRRC regulation 
Since new criterion released by SRRC (State Radio Regulatory Commission,
China) is stricter, we have adjusted TX power limit tables for it. But,
due to RTL8821C HW characteristic, we still need to use specific parameter
in CCK TX filter when set channel to avoid violations in some corner cases.
