This series adds minimal support for Microchip Polar Fire Soc Icicle kit.
It is rebased on v5.10-rc3 and depends on clock support.
Only MMC and ethernet drivers are enabled via this series.
The idea here is to add the foundational patches so that other drivers
can be added to on top of this. The device tree may change based on
feedback on bindings of individual driver support patches.
This series has been tested on Qemu and Polar Fire Soc Icicle kit.
The following qemu series is necessary to test it on Qemu.
The series can also be found at.
https://github.com/atishp04/linux/tree/polarfire_support_upstream_v2
I noticed the latest version of mmc driver[2] hangs on the board with
the latest clock driver. That's why, I have tested with the old clock
driver available in the above github repo.

@Cyril: I have added you as the maintainer for this board as I am not sure
who else from Microchip should be the added to the maintainer list. Please
let me know and I can add the entry to the MAINTAINERS file in next version.
Changes from v1->v2:
1. Modified the DT to match the device tree in U-Boot.
2. Added both eMMC & SDcard entries in DT. However, SD card is only enabled
as it allows larger storage option for linux distros.
