ipq40xx: fix 5Ghz tx/rx power on the ASUS MAP-AC2200

Browse Source 
The ASUS MAP-AC2200 suffers from a lower transmit/receive
signal power as compared to the stock firmware.

Upon investigation, it was discovered that stock firmware from
the GPL_MAP-AC2200_3.0.0.4.384.46249-g97d05bb.tar archive.
set the following GPIOs in "release/src/router/rc/init.c".

GPIO 44 and 46 have to be set to output high
GPIO 45 and 47 have to be set to output low
