hw/misc/xlnx-versal-cframe-reg: Free FIFO, g_tree on deinit
In the xlnx-versal-cframe-reg device we create a FIFO in
instance_init but don't destroy it on deinit, causing ASAN
to report a leak in the device-introspect-test:
Direct leak of 400 byte(s) in 1 object(s) allocated from:
#0 0x5aded4d54e23 in malloc (/mnt/nvmedisk/linaro/qemu-from-laptop/qemu/build/arm-asan/qemu-system-aarch64+0x24ffe23) (BuildId: 9f1e6c53fecd904ba5fc1f521d7da080a0e4103b)

Similarly, we don't clean up the g_tree we create:
Direct leak of 48 byte(s) in 1 object(s) allocated from:
#0 0x5aded4d54e23 in malloc (/mnt/nvmedisk/linaro/qemu-from-laptop/qemu/build/arm-asan/qemu-system-aarch64+0x24ffe23) (BuildId: 9f1e6c5

5)
#3 0x5aded582b21a in cframe_reg_init /mnt/nvmedisk/linaro/qemu-from-laptop/qemu/build/arm-asan/../../hw/misc/xlnx-versal-cframe-reg.c:691:18
Add an instance_finalize method to clean up what we
allocated in instance_init.
