From: Fabio Estevam <festevam@xxxxxxx>
The fsl-imx-mmc hardware needs two clocks to operate: ipg and per.
Document these required clocks.
This fixes the following schema warning:
imx27-apf27dev.dtb: mmc@10014000: Unevaluated properties are not allowed ('clock-names', 'clocks' were unexpected)
from schema $id: http://devicetree.org/schemas/mmc/fsl-imx-mmc.yaml#
Signed-off-by: Fabio Estevam <festevam@xxxxxxx>

Changes since v2:
- None. Just fixed a typo in the dt list.
