ibft: Fix finding IBFT ACPI table on UEFI
commit 935a9fee51c945b8942be2d7b4bae069167b4886 upstream.
Found one system with UEFI/iBFT, kernel does not detect the iBFT during
iscsi_ibft module loading.
Root cause: on x86 (UEFI), we are calling of find_ibft_region() much earlier
- specifically in setup_arch() before ACPI is enabled.
Try to split acpi checking code out and call that later
At that time ACPI iBFT already get permanent mapped with ioremap.
So isa_virt_to_bus() will get wrong phys from right virt address.
We could just skip that phys address printing.
For legacy one, print the found address early.
-v2: update comments and description according to Konrad.
-v3: fix problem about module use case that is found by Konrad.
-v4: use acpi_get_table() instead of acpi_table_parse() to handle module use case that is found by Konrad again..
