mtd: rawnand: qcom: Fix read len for onfi param page 



The minimum size to fetch the data from device to QPIC buffer
is 512-bytes. If size is less than 512-bytes the data will not be
protected by ECC as per QPIC standard. So while reading onfi parameter
page from NAND device set nandc->buf_count = 512.
