VME: Stop using memcpy_[to|from]io() due to unwanted behaviour
The ca91cx42 and tsi148 VME bridges use the width of reads and writes on the PCI bus in part to control the width of the cycles on the VME bus. It is important that we can control the width of cycles on the VME bus as some VME hardware requires cycles of a specific width. The memcpy_toio() and memcpy_fromio() functions do not provide sufficient control, so instead loop using ioread functions.
