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.
