Boris Brezillon 4c7e95b1b3 mtd: nand: gpmi: Fix subpage reads
Commit 25f815f66a ("mtd: nand: force drivers to explicitly send
READ/PROG commands") added a call to nand_read_page_op() in
gpmi_ecc_read_page(), which means this function now sends a READ0
command and place the data pointer at the beginning of the page. This
logic is breaking gpmi_ecc_read_subpage() which was calling
gpmi_ecc_read_page() and expected it to only retrieve the data without
sending the READ0 command.

Create a gpmi_ecc_read_page_data() helper which only does the data
retrieval and ECC correction steps and implement gpmi_ecc_read_page()
as a wrapper that calls nand_read_page_op()+gpmi_ecc_read_page_data().

This way, gpmi_ecc_read_subpage() can call gpmi_ecc_read_page_data()
which restores the logic we had before commit 25f815f66a ("mtd: nand:
force drivers to explicitly send READ/PROG commands").

Fixes: 25f815f66a ("mtd: nand: force drivers to explicitly send READ/PROG commands")
