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.

Either this paragraph...

Or this. Don't say twice the same. Second paragraph is more relevant, so:
"Enable BST SoC and MMC drivers for BST 1200 board".

Thank you for your review. I will refine the commit messages based on your
suggestions.
