spi: spi-mem: export spi_mem_default_supports_op()

Browse Source 
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.
