Some boards need to access GPIOs to determine which SDRAM is fitted to the
board, for example chromebook_link. Probe this device (if it exists) to
make sure that this works as expected.

The ACPI tables are special in that they are passed to EFI as a separate
piece, independent of other tables.
Also they can be spread over two areas of memory, e.g. with QEMU we end
up with tables kept in high memory as well.
Add new global_data fields to hold this information and update the bdinfo
command to show the table areas.
Move the rom_table_end variable into the loop that uses it.

The implementation of write_tables() is confusing because it uses the
rom_table_start variable as the address pointer as it progresses.
Rename it to rom_addr to make the code clearer. Move the rom_table_end
variable into the block where it is used.
Also update logging to use the ACPI category, now that it is available.

This build can be used to boot standard distro builds, since these are
mostly 64-bit these days. Enable some more options, so that all possible
EFI UUIDs are decoded, we get a proper printf() in SPL, can search
memory for tables, support the full set of standard-boot features, have
full logging and can boot from CDROM media.

When global_data is relocated, log_head moves in memory, meaning that

Disable logging when making the change, then reenable it afterwards, so

Enable the various options needed for display to work on the qemu-x86_64
board. This includes expanding the available malloc() memory in SPL,
since the PCI bus must be enumerated in order to find the video device.
It also includes enabling a bloblist, so that the video parameters can be
passed. This is placed at address 10000 but is not needed after U-Boot
proper reads the information there.

Print the banner in SPL init only if the spl_board_init() function isn't

At present this leaves the stack at the pre-relocation value. This is not
ideal since we want to have U-Boot running entirely from the top of
memory.
In addition, the new global_data pointer is not actually used, since
the global_data pointer itself is relocated, then the pre-relocation value
is changed, so the effective value (after relocation) does not update.
Adjust the implementation to follow the 32-bit code more closely, with a
trampoline function which is passed the new stack and global_data pointer.
This ensures that the correct values come through even when relocating.
