Subject: [PATCH v3 7/8] arm64: defconfig: enable BST platform and SDHCI controller support

Enable support for Black Sesame Technologies (BST) platform and drivers
in the ARM64 defconfig:

- CONFIG_ARCH_BST: Enable BST SoC platform support
- CONFIG_MMC_SDHCI_BST: Enable BST C1200 DWCMSHC SDHCI controller driver

This enables eMMC/SD card access on Black Sesame Technologies C1200 series
SoCs. The SDHCI driver provides hardware-specific implementation for the
Synopsys DesignWare Mobile Storage Host Controller integrated in BST SoCs.

Change for v3:
- Also enable CONFIG_ARCH_BST in arm64 defconfig (in addition to
CONFIG_MMC_SDHCI_BST)

Change for v2:
- No changes.
