[PATCH 06/14] mtd: rawnand: gpmi: read buf in nand_read_page_op

[Sascha Hauer <s.hauer@xxxxxxxxxxxxxx>]

The driver calls nand_read_page_op without a buffer passed and then
calls chip->legacy.read_buf to read the buffer afterwards which is
the same as passing the buffer nand_read_page_op in the first place.
