The PL011 TRM (ARM DDI 0183G) specifies that the UART must be
disabled before any of the control registers are programmed. The
PL011 driver included in TF does not disable the UART, so the
initialization in BL2 and BL31 is violating this requirement
(and potentially in BL1 if the UART is enabled after reset).
This patch modifies the initialization function in the PL011
console driver to disable the UART before programming the
control registers.
Register clobber list and documentation updated.
Fixes ARM-software/tf-issues#300

Migrate all direct usage of __attribute__ to usage of their
corresponding macros from cdefs.h.
e.g.:
- __attribute__((unused)) -> __unused

This patch update Mediatek port to use the `DEFINE_BAKERY_LOCK` macro instead of
specifying the exact data structure to use for a bakery lock and the input
linker section that it should be allocated to.
