refactor(arm): console runtime switch on bl31 exit

Any BL31 setup and Runtime initialization within BL31 is still part of
the BOOT process. As such, the console flush and switch must be the
last calls before BL31 exit. Flush the console print buffer before
switching to runtime. This is so that there is no lingering chars in
the print buffer when we move to the runtime console.

This patch adds console flush before switching to runtime in
bl31_plat_runtime_setup() function (before BL31 exits). The plan is to
move flush and switch calls to bl31_main before BL31 exits, until then
console_flush() in bl31_main.c has been left as is.

This patch affects the Arm platform only.
