ead7077360 memstick: automatically retrieve "INT" value from command response
MemoryStick storage cards, when in parallel mode, send several meaningful bits
of their "INT" register as part of command response.  This data is stored by
host and can be used to spare invocation of "GET_INT" TPC on each data page
transferred between host and card.
