bcma: fix incorrect update of BCMA_CORE_PCI_MDIO_DATA
An earlier commit re-worked the setting of the bitmask and is now assigning v with some bit flags rather than bitwise or-ing them into v, consequently the earlier bit-settings of v are being lost. Fix this by replacing an assignment with the bitwise or instead.
