Subject: spi: spi-mem: export spi_mem_default_supports_op()

Git-commit: 46109648052fe778c75f199d72255c899578d6f7
Patch-mainline: v5.2-rc1
References: bsc#1175421

Export spi_mem_default_supports_op(), so that controller drivers
can use this.
spi-mem driver already exports this using EXPORT_SYMBOL,
but not declared it in spi-mem.h.
This patch declares spi_mem_default_supports_op() in spi-mem.h and
also removes the static from the function prototype.
