x86/PVH: Use boot params to pass RSDP address in start_info page
After commit e6e094e053af75 ("x86/acpi, x86/boot: Take RSDP address from
boot params if available"), the RSDP address can be passed in boot
params. Therefore, store the RSDP address in start_info page into boot
params in the PVH entry instead of registering a different callback.
This removes an absolute reference during the PVH entry and is more
standardized.
