[PATCH] Revert "OMAP/serial: Fix incorrect Rx FIFO threshold setting, LSR validation on Tx, and Tx FIFO IRQ generation"

[Alexey Pelykh]

Hi Paul,

No problem, I'll prepare patch in next 24 hours and will send in ASAP.

But, since we've found the issue, I suggest that we should look at it
closer, especially since at this moment only you can reproduce it. As
far as I understand, but I may be wrong,
this comment is wrong, since if to specify
OMAP_UART_SCR_RX_TRIG_GRANU1_MASK, it effectively sets Rx threshold to
1 character, instead of 16.
/* Set receive FIFO threshold to 16 characters and
 * transmit FIFO threshold to 16 spaces
 */
