init: Call mem_encrypt_init() after Hyper-V hypercall init is done
Full Hyper-V initialization, including support for hypercalls, is done
as an apic_post_init callback via late_time_init(). mem_encrypt_init()
needs to make hypercalls when it marks swiotlb memory as decrypted.
But mem_encrypt_init() is currently called a few lines before
late_time_init(), so the hypercalls don't work.
Fix this by moving mem_encrypt_init() after late_time_init() and
related clock initializations. The intervening initializations don't
do any I/O that requires the swiotlb, so moving mem_encrypt_init()
slightly later has no impact.
