[PATCH v3 3/3] xen/riscv: finalize boot allocator and transition to boot state

[Oleksii Kurochko <oleksii.kurochko@xxxxxxxxx>]

Add a call to end_boot_allocator() in start_xen() to finalize the
boot memory allocator, moving free pages to the domain sub-allocator.

After initializing the memory subsystem, update `system_state` from
`SYS_STATE_early_boot` to `SYS_STATE_boot`, signifying the end of the
early boot phase.
