ARM: dts: imx7-colibri: Fix frequency for sd/mmc
SD/MMC on Colibri iMX7S/D modules successfully support
200Mhz frequency in HS200 mode.
Removing the unnecessary max-frequency limit significantly
increases the performance:
== before fix ====
root@colibri-imx7-emmc:~# hdparm -t /dev/mmcblk0
/dev/mmcblk0:
Timing buffered disk reads: 252 MB in 3.02 seconds = 83.54 MB/sec
==================
=== after fix ====
root@colibri-imx7-emmc:~# hdparm -t /dev/mmcblk0
/dev/mmcblk0:
Timing buffered disk reads: 408 MB in 3.00 seconds = 135.94 MB/sec
==================
