mtd: rawnand: davinci: Avoid duplicated page read
The function nand_davinci_read_page_hwecc_oob_first() first reads the
OOB data, extracts the ECC information, programs the ECC hardware before
reading the actual data in a loop.
Right after the OOB data was read, it called nand_read_page_op() to
reset the read cursor to the beginning of the page. This caused the
first page to be read twice: in that call, and later in the loop.
Address that issue by changing the call to nand_read_page_op() to
nand_change_read_column_op(), which will only reset the read cursor.
