Align the prototype of send_dest_ipi_mask() on x86 with the RISC-V
definition. dest_mask is updated from uint32_t to uint64_t:
From: void send_dest_ipi_mask(uint32_t dest_mask, uint32_t vector)
To: void send_dest_ipi_mask(uint64_t dest_mask, uint32_t vector)
On RISC-V, send_dest_ipi_mask() is implemented using SBI interfaces,
where the dest_mask is defined as "unsigned long" in the SBI spec.
