spi: spi-mem: Allow controller supporting mem_ops without exec_op
Currently exec_op is always required if controller driver provides
mem_ops. But some controller such as bcm63xx-hsspi may only need to
implement other operation like supports_op and use the default
execution operation. This patch removes this restriction.
