Drivers: hv: vmbus: Optimize boot time by concurrent execution of hv_synic_init()
Currently on a very large system with 1780 CPUs, hv_acpi_init() takes
around 3 seconds to complete. This is because of sequential synic
initialization for each CPU performed by hv_synic_init().
Schedule these tasks parallelly so that each CPU executes hv_synic_init()
in parallel to take full advantage of multiple CPUs.
This solution saves around 2 seconds of boot time on a 1780 CPU system,
which is around 66% improvement in the existing logic.
