uniphier: make all BL images completely position-independent

This platform supports multiple SoCs. The next SoC will still keep
quite similar architecture, but the memory base will be changed.

The ENABLE_PIE improves the maintainability and usability. You can reuse
a single set of BL images for other SoC/board without re-compiling TF-A
at all. This will also keep the code cleaner because it avoids #ifdef
around various base addresses.

By defining ENABLE_PIE, BL2_AT_EL3, BL31, and BL32 (TSP) are really
position-independent now. You can load them anywhere irrespective of
their link address.

uniphier: support console based on multi-console

The legacy console is gone. Re-add the console support based on the
multi-console framework.

I am still keeping the putc, getc, and flush callbacks in
uniphier_console.S to use plat/common/aarch64/crash_console_helpers.S

The console registration code already relies on that C environment
has been set up. So, I just filled the struct console fields with the
callback pointers, then called console_register() directly. I also
re-implemented the init function in C to improve the readability.

Removing the custom crash console implementation has one disadvantage;
we cannot use the crash console on very early crashes because
crash_console_helpers.S works only after the console is registered.
I can live with this limitation.

Tested on my boards, and confirmed this worked like before.

uniphier: set PROGRAMMABLE_RESET_ADDRESS to disable warm boot mailbox

The warm boot mailbox code is compiled if PROGRAMMABLE_RESET_ADDRESS
is disabled.

The warm boot mailbox is useless for UniPhier SoC family because BL1
is not the first image. The UniPhier platform implements non-TF ROM,
then BL1 works as a pseudo ROM, so it is never executed in the warm
boot.

The reset vector address is not actually programmable for UniPhier
platform, but it should not hurt to enable PROGRAMMABLE_RESET_ADDRESS
to disable the mailbox and remove pointless plat_get_my_entrypoint.

uniphier: make sure to create build directory before ROT key

Building the UniPhier platform in parallel with TRUSTED_BOARD_BOOT=1
could fail due to non-existing directory. It might be difficult to
reproduce, but here is an easier way to trigger the problem:

$ make PLAT=uniphier TRUSTED_BOARD_BOOT=1 MBEDTLS_DIR=mbedtls certificates
OPENSSL build/uniphier/release/rot_key.pem
/bin/sh: 1: cannot create build/uniphier/release/rot_key.pem: Directory nonexistent
make: *** [build/uniphier/release/rot_key.pem] Error 2

The $(ROT_KEY) must depend on $(BUILD_PLAT) so that the build directory
is created before the key.
