drivers: ti: uart: remove UART_FCR writes
...
This patch removes the code that touched UART_FCR, from
console_core_putc(). The check for whether transmit FIFO is
full is sufficient before writing to UART TX FIFO. In fact
setting UARTFCR_TXCLR immediately after a byte is written to
FIFO might even result in loss of that byte, if UART hasn't
sent that byte out yet.

Add console_core_flush() in upstream platforms
...
It is needed to add placeholders for this function because, as this is
not a `plat_xxx()` function, there aren't weak definitions of it in any
file.
If `console_flush()` is used and there isn't an implementation of
`console_core_flush()` in any file, the compilation will fail.

uart: 16550: Fix getc
...
tbz check for RDR status is to check for a bit being zero.
Unfortunately, we are using a mask rather than the bit position.
Further as per http://www.ti.com/lit/ds/symlink/pc16550d.pdf (page 17),
LSR register bit 0 is Data ready status (RDR), not bit position 2.
Update the same to match the specification.

Move console drivers to AArch64 folder
...
This patch moves the various assembly console drivers
into `aarch64` architecture specific folder. Stub files,
which include files from new location, are retained at the
original location for platform compatibility reasons.
