wifi: rtw88: 8821c: Fix beacon loss and disconnect
Tenda U9 V2.0, which contains RTL8811CU, is practically unusable because
of frequent disconnections:

This is caused by a mistake in the chip initialisation. This version of
the chip requires loading an extra AGC table right after the main one,
but the extra table is being loaded at the wrong time, in
rtw_chip_board_info_setup().
Move the extra AGC table loading to the right place, in
rtw_phy_load_tables().
The rtw_chip_board_info_setup() can only do "software" things, and
rtw_phy_load_tables() can really do IO.
