Disable dynamic current limit for ttpci budget cards.
According to the ISL6423 datasheet, if dynamic current limiting is turned on,
the static limit is ignored and the current drawn can be as high as 990mW.
This is not what we want as it might overload the PCI bus. Disabling
dynamic limit also avoid issues with rotors and DiSEqC switches which
might require a higher current for a short period when powered on.
