Juan Castillo 9400b40ea4 Disable PL011 UART before configuring it ... 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.
