ARM: dts: colibri-imx7: limit eMMC SDHC frequency to 100MHz
During temperature testing modules print the following error every
now and then:
[ 12.231006] mmc0: Timeout waiting for hardware interrupt. retries left=0 opcode=12
Often the SDHC controller/driver does not recover from the issue
which leads to a Kernel panic (e.g. during boot the kernel can not
mount the root fs).
Lowering the frequency to 100MHz proves to be stable and affects
effective bandwith by less than 5%.
