[PATCH 2/4] dmaengine: at_xdmac: fix AT_XDMAC_CC_PERID() macro

[Claudiu Beznea]

AT_XDMAC_CC_PERID() should be used to setup bits 24..30 of XDMAC_CC
register. Using it without parenthesis around 0x7f & (i) will lead to
setting all the time zero for bits 24..30 of XDMAC_CC as the << operator
has higher precedence over bitwise &. Thus, add paranthesis around
0x7f & (i).
