Subject: [PATCH 4/5] ARM: dts: imxrt1050: remove mmc max-frequency property

According to i.MXRT1050 Reference Manual usdhc supports up to 208Mhz clock
so let's remove max-frequency property in the .dtsi base file and
in case add that property in the board specific .dts file for a specific
device connected to it.
