Subject: [PATCH 5.15 123/135] arm64: dts: ti: k3-am64-main: Remove support for HS400 speed mode

From: Aswath Govindraju <a-govindraju@...com>

commit 0c0af88f3f318e73237f7fadd02d0bf2b6c996bb upstream.

AM64 SoC, does not support HS400 and HS200 is the maximum supported speed
mode[1]. Therefore, fix the device tree node to reflect the same.
