pcmcia: Implement CLKRUN protocol disabling for Ricoh bridges
Currently, "disable_clkrun" yenta_socket module parameter is only implemented for TI CardBus bridges. Add also an implementation for Ricoh bridges that have the necessary setting documented in publicly available datasheets. Tested on a RL5C476II with a Sunrich C-160 CardBus NIC that doesn't work correctly unless the CLKRUN protocol is disabled. Let's also make it clear in its description that the "disable_clkrun" module parameter only works on these two previously mentioned brands of CardBus bridges. Signed-off-by: Maciej S.
