- Reimplemented FifoReset in other way, only call to GPFifo::ResetGatherPipe() ResetVideoBuffer() in FIFO_RW_DISTANCE_LO when this is equal to "0"

Browse source 
- In the Command Processor Control Register when GPReadEnable is OFF, wait until the fifo lopp finish with thi actual 32 bytes block. This is necessary to have Safe Disabble GP Read in this way AbortFrame is performed by the software, beside this can help to have accurate GPReadEnable OFF.
Please test Metroid Prime 1/2, Guilty Gear XX, X men gc, SMG, and shuffle you can test Harry Potter Prince for WII. :)

PD: The fifo code need a clean very soon.
