platform: Remove the ipi_sync method from all platforms.

Browse Source 
OpenSBI manages outstanding TLB flush requests by queueing
them in a fifo synchronously. An ipi sync which uses an
atomic operation on MMIO address is no longer required.

Remove the ipi sync method from platform header and all usage.
