mtd: rawnand: meson: fix bit map use in meson_nfc_ecc_correct()

stable inclusion

commit 7bd5f3b4a805036892da047010b43d067603b139
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I6D0XA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=7bd5f3b4a805036892da047010b43d067603b139



--------------------------------

[ Upstream commit 3e4ad321 ]

The meson_nfc_ecc_correct() function accidentally does a right shift
instead of a left shift so it only works for BIT(0).  Also use
BIT_ULL() because "correct_bitmap" is a u64 and we want to avoid
shift wrapping bugs.
