BCDMA: BCDMA RX_IGNORE_LONG setting in RX CHAN CFG register doesn't work

Details:

RX_IGNORE_LONG flag in RXCHAN CFG register of BCDMA gets ignored and BCDMA reports errors in TR response when remote endpoints don't send EOP to match TR boundary.

Workaround(s):

RX_IGNORE_LONG is unusable, so remote endpoint such as PDMA should close packet by sending EOP to match TR boundary (PDMA X*Y*Z should match TR ICNT0*ICNT1*ICNT2*ICNT3)

If infinite stream is desired (PDMA Z=0) then switch to PKTDMA and use Single Buffer Mode
