[DistroKit] [PATCH v3 09/14] v7a: kernel: enable features necessary for RAUC

[Roland Hieber <rhi@pengutronix.de>]

Enable the following kernel features:

* ARM SHA256 acceleration (CRYPTO_SHA256_ARM)
* Device mapper support (MD, BLK_DEV_DM)
* Verity target support (DM_VERITY), needed for the verity bundle format
* squashfs file system (MISC_FILESYSTEMS, SQUASHFS*, XZ_DEC_*, LZ4_*),
  also having multiple compression algorithms enabled for squashfs makes
  it easy to change the compression of the RAUC bundle in the future
* Network block device support (BLK_DEV_NBD), needed for HTTPS streaming
