Currently, for some small (1/4/8 bytes) transfers, the driver uses
on-stack memory to perform the transfer. This is not safe as the
underlying master/dma driver could try to map/dma this memory.
Change makes sure to never use on-stack memory for any transfers.

It is possible that the spi transfer that clears the clock request
on the slave may fail. In such case, it is not safe to assume that
the clock request is still enabled as it can cause failures for
further spi transfers if the clock request is cleared. Fix such
issues by resetting the clock state in the driver even the clock
request clearing fails.

Variable 'status' is used without initialization.
Initialize it to the right value.
