Neeraj Soni fd78e2b582 mmc: sdhci-msm: Add support for wrapped keys 
Add the wrapped key support for sdhci-msm by implementing the needed
methods in struct blk_crypto_ll_ops and setting the appropriate flag in
blk_crypto_profile::key_types_supported.

Tested on SC7280 eMMC variant.

How to test:

Use the "v1.3.0" tag from https://github.com/google/fscryptctl and build
fscryptctl that supports generating wrapped keys.

Enable the following config options:
CONFIG_BLK_INLINE_ENCRYPTION=y
CONFIG_QCOM_INLINE_CRYPTO_ENGINE=y
CONFIG_FS_ENCRYPTION_INLINE_CRYPT=y
CONFIG_MMC_CRYPTO=y

Enable "qcom_ice.use_wrapped_keys" via kernel command line.

$ mkfs.ext4 -F -O encrypt,stable_inodes /dev/disk/by-partlabel/vm-data
$ mount /dev/disk/by-partlabel/vm-data -o inlinecrypt /mnt
$ fscryptctl generate_hw_wrapped_key /dev/disk/by-partlabel/vm-data > /mnt/key.longterm
$ fscryptctl prepare_hw_wrapped_key /dev/disk/by-partlabel/vm-data < /mnt/key.longterm > /tmp/key.ephemeral
$ KEYID=$(fscryptctl add_key --hw-wrapped-key < /tmp/key.ephemeral /mnt)
$ rm -rf /mnt/dir
$ mkdir /mnt/dir
$ fscryptctl set_policy --iv-ino-lblk-32 "$KEYID" /mnt/dir
$ dmesg > /mnt/dir/test.txt
$ sync

Reboot the board

$ mount /dev/disk/by-partlabel/vm-data -o inlinecrypt /mnt
$ ls /mnt/dir # File should be encrypted
$ fscryptctl prepare_hw_wrapped_key /dev/disk/by-partlabel/vm-data < /mnt/key.longterm > /tmp/key.ephemeral
$ KEYID=$(fscryptctl add_key --hw-wrapped-key < /tmp/key.ephemeral /mnt)
$ fscryptctl set_policy --iv-ino-lblk-32 "$KEYID" /mnt/dir
$ cat /mnt/dir/test.txt # File should now be decrypted
