[PATCH v3 04/22] wifi: rtw88: Extend the init table parsing for RTL8812AU

[Bitterblue Smith <rtl8821cerfe2@gmail.com>]

The chips supported so far only use the first condition, and so the
parsing code ignores the second condition. RTL8812AU's init tables use
the second condition also. Make the parsing code check it.

v2:
 - Initialise structs with {} instead of {0}.

v3:
 - Check for !(cond.rfe & 0x0f) in order to reduce the indentation
   level.
