This function ensures that console output is flushed, for example
before shutting down or use by another component

In line with other console APIs, console_flush() wraps
console_core_flush().

Also implement console_core_flush() for PL011.

This patch makes following miscellaneous fixes:
* pl011_console.S: Fixed the bit mask used to check if the
  transmit FIFO is full or empty.
* smcc_macros.S: Added `_fsxc` suffix while updating the SPSR.
  By default the assembler assumes `_fc` suffix which does not
  update all the fields in SPSR. By adding `_fsxc` suffix all
  the fields gets updated.
* platform_helpers.S: Removed the weak definition for
  `plat_my_core_pos()` as this is a mandatory function which
  needs to be defined by all platforms.
