Subject: [PATCH v4] ARM: dts: imxrt1050: increase mmc max-frequency property

According to i.MXRT1050 Datasheet usdhc supports up to 200Mhz clock so
let's increase max-frequency property to 200Mhz.

V1->V2:
* set max-frequency to 200Mhz instead of removing it as suggested by
  Bough Chen
V2->V3:
* added Jesse Taube's Acked-by:
