rtl8xxxu: hide unused tables

rtl8xxxu: hide unused tables

The references to some arrays in the rtl8xxxu driver were moved inside
of an #ifdef, but the symbols remain outside, resulting in build warnings:

rtl8xxxu/rtl8xxxu.c:1506:33: error: 'rtl8188ru_radioa_1t_highpa_table' defined but not used
rtl8xxxu/rtl8xxxu.c:1431:33: error: 'rtl8192cu_radioa_1t_init_table' defined but not used
rtl8xxxu/rtl8xxxu.c:1407:33: error: 'rtl8192cu_radiob_2t_init_table' defined but not used
rtl8xxxu/rtl8xxxu.c:1332:33: error: 'rtl8192cu_radioa_2t_init_table' defined but not used
rtl8xxxu/rtl8xxxu.c:239:35: error: 'rtl8192c_power_base' defined but not used
rtl8xxxu/rtl8xxxu.c:217:35: error: 'rtl8188r_power_base' defined but not used

This adds an extra #ifdef around them to shut up the warnings.
