ARM: dts: imx7-colibri: Fix frequency for eMMC
eMMC, used in Colibri iMX7D eMMC modules, supports
200Mhz mode with vccq=1.8v.
Remove the max-frequency limit, it increases the performance significantly:
== before fix ====
root@colibri-imx7-emmc:~# hdparm -t /dev/mmcblk1
/dev/mmcblk1:
Timing buffered disk reads: `^H252 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
==================
