From: YueHaibing <yuehaibing@huawei.com>

When building with CONFIG_SPI_MEM is not set
gc warns this:

drivers/spi/spi-zynq-qspi.o: In function `zynq_qspi_supports_op':
spi-zynq-qspi.c:(.text+0x1da): undefined reference to `spi_mem_default_supports_op'

Fixes: 67dca5e580f1 ("spi: spi-mem: Add support for Zynq QSPI controller")

v2: make stub helper static inline
