hv: remove hardcoding of SW SRAM HPA base

Browse Source 
Physical address to SW SRAM region maybe different
 on different platforms, this hardcoded address may
 result in address mismatch for SW SRAM operations.

 This patch removes above hardcoded address and uses
 the physical address parsed from native RTCT.
