Subject: [PATCH v4 0/3] mmc: Adding support for Microchip Sparx5 SoC

(This is a resend of an identical patch set, sent at a time where
Sparx5 support was not integrated yet. With the Sparx5 clock driver
and associated header now in place in the v5.9rc series, the driver is
now resubmitted for inclusion).

The patch adds eMMC support for Sparx5, by adding a driver for the SoC
SDHCI controller, DT configuration and DT binding documentation.

Changes in v4:
- Disable clock if sdhci_add_host() fails
- Remove dev_err if sdhci_add_host() fails

Changes in v3:
- Add dt-bindings for property "microchip,clock-delay"
- Enforce "microchip,clock-delay" valid range in driver
- Removed a noisy pr_debug() in sdhci_sparx5_adma_write_desc()

Changes in v2:
- Changes in driver as per review comments
 - Drop debug code
 - Drop sysfs code
 - use usleep_range()
 - use mmc_hostname() in pr_debug()
 - Remove deactivated code
 - Minor cosmetics
