[PATCH v7 0/2] arm64: dts/defconfig: enable BST C1200 eMMC

This series adds DTS and defconfig support for the eMMC controller
on Black Sesame Technologies C1200 SoC, split from the v5 MMC series [1].

The MMC driver patches (dt-bindings, sdhci bounce buffer, BST SDHCI driver,
and MAINTAINERS update) have been applied to mmc-next by Ulf Hansson [2].
These remaining DTS and defconfig patches are submitted for review on the
mailing lists first, per Krzysztof's feedback on v6 [3].

Changes since v6:
- No code changes. Resend with corrected recipients: send to mailing
lists for review first, not directly to soc@ (BST has a platform
maintainer in MAINTAINERS).

Changes since v5:
- Patch 2 (defconfig): fix CONFIG_MMC_SDHCI_BST ordering to match Kconfig
position (between CONFIG_MMC_SDHCI_TEGRA and CONFIG_MMC_SDHCI_F_SDH30),
as pointed out by Krzysztof Kozlowski. Confirmed via savedefconfig.
