hv: remove the hardcoding of Software SRAM GPA base

Browse Source 
Currently, we hardcode the GPA base of Software SRAM
 to an address that is derived from TGL platform,
 as this GPA is identical with HPA for Pre-launch VM,
 This hardcoded address may not work on other platforms
 if the HPA bases of Software SRAM are different.

 Now, Offline tool configures above GPA based on the
 detection of Software SRAM on specific platform.

 This patch removes the hardcoding GPA of Software SRAM,
 and also renames MACRO 'SOFTWARE_SRAM_BASE_GPA' to
 'PRE_RTVM_SW_SRAM_BASE_GPA' to avoid confusing, as it
 is for Prelaunch VM only.
