[riot-users] Manipulate CPU Register on samr21-xpro

Hello guys,

I'm using some samr21-xpro boards and the output radio power of the
modul is very strong.
I want to reduce the power a little bit. The datasheet ([1],  Page 979 -
980) says, I have to manipulate register
"PHY_TX_PWR" (Address 0x5).

Does anyone have an idea how the implementation looks like in C.
