mtd: rawnand: marvell: don't set the NAND frequency select

stable inclusion

commit 9823ac6e7ae19f08e6d2c73bbc3b2d956e823823
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I8IRR2

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=9823ac6e7ae19f08e6d2c73bbc3b2d956e823823



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

[ Upstream commit c4d28e30 ]

marvell_nfc_setup_interface() uses the frequency retrieved from the
clock associated with the nand interface to determine the timings that
will be used. By changing the NAND frequency select without reflecting
this in the clock configuration this means that the timings calculated
don't correctly meet the requirements of the NAND chip. This hasn't been
an issue up to now because of a different bug that was stopping the
timings being updated after they were initially set.
