Fix writing U-Boot environment on ODROID-M1 (#3510)

Browse Source 
Apply the same patch we applied in #3412 for Green. At that time I thought the
patch was already applied upstream for M1 and haven't checked, but it turns out
it wasn't true. Apply it here before we get U-Boot with that patch series [1]
included.

Subject: [PATCH] odroid-m1: Disable eMMC DDR52 mode, enable HS200
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Disable DDR52 mode on odroid-m1 to fix eMMC writes. Also enable HS200,
as it's supposed to work more reliably than slower modes.
