This fixes the MMC failing to initialize on newer ZyXEL NBG6817
hardware revisions with Kingston MMC. Older revisions should
hopefully be unaffected.
Check MMC hardware details with:
cd /sys/block/mmcblk0/device/ && \
tail -v cid date name manfid fwrev hwrev oemid rev
Known problematic MMC names (broken before this commit):
* M62704 (dated 12/2018) via myself
* M62704 (dated 11/2018) via Drake Stefani
Known unaffected MMC names (already working without this commit):
* S10004 (dated 12/2015) via slh
Now, the MMC properly initializes and later switches to high speed.
Thanks to:
* Ansuel for maintaining/help with the IPQ806x platform, kernel code
* slh for additional debugging and suggestions
* dwfreed for confirming newer MMC details, clock frequency
* robimarko for device driver debug printing help, clock debugging
* Drake for testing and confirmation with their own newer NBG6817
...and anyone else I missed!

The difference between flashing:
Interrupt U-Boot and run these commands:
setenv bootcmd "setenv mtdids nand0=nand0 && set mtdparts
mtdparts=nand0:0xDC00000@0x2400000(firmware) && ubi part firmware &&
ubi read 0x44000000 kernel 0x6e0000 && bootm"
saveenv
* ipq806x: fix missing changes in 5.4 for new cpufreq implementation
The new cpufreq dedicated driver changed the node structure
on how the cache should be defined in the dts. The 5.4 dtsi addition
patch has not been updated to follow the new implementation.
Fix this to restore correct cache scaling and restore any performance
regression.

* ipq806x: fix missing 1.4ghz cache freq for ipq8065 SoC
With the new implementation of the dedicated cpufreq driver,
the 1.4 Ghz was only dropped and not added to the ipq8065 SoC.
Fix this to improve performance.

* ipq806x: fix dedicated cpufreq driver
2 small fix for the dedicated cpufreq driver:
- Fix index wrongly used as the current cpu
- Exit early if a bad freq is detected. In the current state the freq
is applied anyway even with invalid state.
