libpayload: Always use virtual pointers in struct sysinfo_t
We had mixed virtual and physical pointers in struct sysinfo_t. Some being virtual by accident which led to problems when we tried to reinitialize lib_sysinfo after relocating FILO (to get intentionally virtual pointers valid again). I guess this didn't cause much trouble before, as lib_get_sysinfo() was always called with physical addresses being equal to their virtual counterparts. For FILO, two possibilities seem practical: Either, have all pointers in struct sysinfo_t physical, so relocation doesn't hurt. Or, have all pointers virtual and call lib_get_sysinfo() again after relocation. This patch goes the latter way, changing the following pointers for situations where virtual pointers differ from physical: .extra_version .build .compile_time .compile_by .compile_host .compile_domain .compiler .linker .assembler .cb_version .vdat_addr .tstamp_table .cbmem_cons .mrc_cache We could also just correct the accidentally virtual pointers. But, IMO, this would lower the risk of future confusion. Note 1: Looks like .version gets never set. Note 2: .option_table and .framebuffer were virtual pointers but treated like physical ones. Even in FILO, this led to no problems as they were set before relocation.
