From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
Currently the expression (nand_ctrl | BAM_MODE_EN) is always true no
matter the value of nand_ctrl because the incorrect masking operator
is being used. Fix this by using bit-wise & instead of |.
Addresses-Coverity: ("Wrong operator used")
Fixes: dd0c1fc8de12 ("mtd: rawnand: qcom: set BAM mode only if not set already")
