firmware_loader: enable XZ by default if compressed support is enabled
Commit 23cfbc6ec44e ("firmware: Add the support for ZSTD-compressed firmware files") added support for ZSTD compression, but in the process also made the previously default XZ compression a config option. That means that anybody who upgrades their kernel and does a make oldconfig to update their configuration, will end up without the XZ compression that the configuration used to have. Add the 'default y' to make sure this doesn't happen. The whole compression question should probably be improved upon, since it is now possible to "enable" compression in the kernel config but not enable any actual compression algorithm, which makes it all very useless. It makes no sense to ask Kconfig questions that enable situations that are nonsensical like that. This at least fixes the immediate problem of a kernel update resulting in a nonbootable machine because of a missed option.

This option adds the support for XZ-compressed files.
The files have to be compressed with either none or crc32
