[efr32] radio: fix otPlatRadioGetTransmitPower (#5932)

Browse Source 
The efr32 platform shows the following behavior:

> txpower -10
Done
>
> txpower
-113 dBm
Done

The bug is caused by the C promotion rules during the division of
int16_t by unsigned in otPlatRadioGetTransmitPower. This commit fixes
the issue.
