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.

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.
