Subject: [PATCH] load modules from vendor_boot ramdisk in TWRP instead of depending on init

Use 'TW_LOAD_VENDOR_BOOT_MODULES := true'
to use TWRP module loader code for vendor_boot module loading.

Some devices need this for successful kernel module loading.

Subject: [PATCH] set data/recovery on devices where the TW_INCLUDE_CRYPTO flag has not been set

On some devices where the cryptography is broken, the maintainers do not set the flag and the data/recovery is not being created, so that at each boot the settings are not saved.
