spi: bcm2835aux: Avoid 64-bit arithmetic in xfer len calc We want to check for xfers that are over 30 microseconds. Rather than find how many µs a xfer will take, instead find how many bytes can be transferred in 30 µs. The latter must be less than 32 bits (since our clock speed is limited to 32 bits), while the former involves 64 bit quantities and more arithmetic operations.
