wifi: rtw89: coex: use struct assignment to replace memcpy() to append TDMA content

To notify firmware TDMA timeslot assignment, append TDMA parameters when
sending policy H2C firmware command. However, compiler warns we do memcpy()
data to val[] field of TLV struct. To avoid this, assign the struct value
with simple '=' instead. Compile tested only.
