Commit 977b8e83cb0a ("mb/emulation/qemu-aarch64: Add MMU support") adds
MMU support for ARM64 QEMU VMs, but registers a limited 1GiB region for
the DRAM, with a note that ramstage should update it.
However on recent versions of QEMU "virt" VMs, accessing RAM outside
this registered region results in an exception even if the address is
backed by actual RAM. This interferes with RAM detection which catches
these exceptions, effectively limiting us to detecting a maximum 1GiB of
RAM even if more is available.
Register the entire RAM space to MMU instead of just the 1GiB, so that
probing RAM addresses can correctly detect how much RAM we have.

Run with "-device pci-bridge,chassis_nr=1" argument to add a bridge and
see that it gets found and picked up by the resource allocator.

This patch changes the memlayout macro infrastructure so that the size
of a region "xxx" (i.e. the distance between the symbols _xxx and _exxx)
is stored in a separate _xxx_size symbol. This has the advantage that
region sizes can be used inside static initializers, and also saves an
extra subtraction at runtime. Since linker symbols can only be treated
as addresses (not as raw integers) by C, retain the REGION_SIZE()
accessor macro to hide the necessary typecast.

Stefan thinks they don't add value.
Command used:
sed -i -e '/file is part of /d' $(git grep "file is part of " |egrep ":( */\*.*\*/\$|#|;#|-- | *\* )" | cut -d: -f1 |grep -v crossgcc |grep -v gcov | grep -v /elf.h |grep -v nvramtool)
The exceptions are for:
- crossgcc (patch file)
- gcov (imported from gcc)
- elf.h (imported from GNU's libc)
- nvramtool (more complicated header)
The removed lines are:

Linux expects a working PSCI and hangs if not found.
Add BL31 into CBFS as '-M virt,secure=on -bios ' commands line arguments cause
qemu's internal PSCI emulation to shutdown.
BL31 is placed in qemu's SECURERAM memory region and won't conflict with
resources in DRAM.
Tested on qemu-system-aarch64:
Fixes a hang and allows to boot into Linux 5.4.14 userspace.

Enable MMU in bootblock. Makes qemu look more similar to real hardware.
There's no real need to activate the MMU.
Tested on qemu-system-aarch64: 5 page entries are used out of 32.
