arm64: dts: mt7986: fix emmc hs400 mode without uboot initialization

stable inclusion
from stable-v6.6.7
commit 90dc20c8c51d13d410776af8d81689afc16183ea
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I8SSQ4

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=90dc20c8c51d13d410776af8d81689afc16183ea

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

commit 8dfe51c3f6ef31502fca3e2da8cd250ebbe4b8f2 upstream.

Eric reports errors on emmc with hs400 mode when booting linux on bpi-r3
without uboot [1]. Booting with uboot does not show this because clocks
seem to be initialized by uboot.

Fix this by adding assigned-clocks and assigned-clock-parents like it's
done in uboot [2].
