exynos: uart: s5p: fix the garbled decompressing linux...message

Fix the garbled decompressing linux...message and by enabling the uart
tx/rx fifo. Now that fifo is enabled, the uart read/write functions
are modfied to check the UFSTAT register for fifo status instead of
UTRSTAT (as required with fifo's enabled).

BUG=none
TEST=booted on daisy, Uncompressing Linux is fine
