rtw88: 8822c: fix missing brace warning for old compilers

For older versions of gcc, the array = {0}; will cause warnings:

drivers/net/wireless/realtek/rtw88/rtw8822c.c: In function 'rtw8822c_power_trim':
>> drivers/net/wireless/realtek/rtw88/rtw8822c.c:1039:2: warning:
>> missing braces around initializer [-Wmissing-braces]
s8 bb_gain[2][8] = {0};
^
drivers/net/wireless/realtek/rtw88/rtw8822c.c:1039:2: warning: (near
initialization for 'bb_gain[0]') [-Wmissing-braces]
