Subject: [PATCH for v4.9 LTS 07/87] ARM: dts: n900: Mark eMMC slot with
 no-sdio and no-sd flags

From: Pali Rohár <pali.rohar@...il.com>

[ Upstream commit 4cf48f1d7520a4d325af58eded4d8090e1b40be7 ]

Trying to initialize eMMC slot as SDIO or SD cause failure in n900 port of
qemu. eMMC itself is not detected and is not working.

Real Nokia N900 harware does not have this problem. As eMMC is really not
SDIO or SD based such change is harmless and will fix support for qemu.
