Increase SDIO CIU frequency from 12500000Hz to 50000000Hz by
switching from the default divisor value (div-by-8) to the
minimum possible value of the divisor (div-by-2) in HSDK platform
code.
Please describe the problem first not the solution. That some SD cards don't work
blah blah ....
You could add me as reported-by - just for completeness !

While I will test it to see if it cures my issue, I'll need Alexey to sign off /
ack as well !
Sure once you update us with your findings and we know it helps you
(at least Bonnie++ stress-test with one of SD-cards here still works)
there will be a "normal" patch which I'll ack.

Thx guys ! Patch cures the issue with my SD card.

Please respin with changelog and Reported-by/Tested-by for me !
