i386/pc: handle unitialized mr in pc_get_cxl_range_end()

Remove pc_get_cxl_range_end() dependency on the CXL memory region,
and replace with one that does not require the CXL host_mr to determine
the start of CXL start.

This in preparation to allow pc_pci_hole64_start() to be called early
in pc_memory_init(), handle CXL memory region end when its underlying
memory region isn't yet initialized.
