Hi All,
Since many panel power sequence request backlight stay disable

So we need this patch. This patch have been fly for a long tim
The F81532/534 had auto RTS direction support for RS485 mode.
We'll read it from internal Flash with address 0x2f01~0x2f04 for 4 ports.
There are 4 conditions below:
0: F81534_PORT_CONF_RS232.
1: F81534_PORT_CONF_RS485.
2: value error, default to F81534_PORT_CONF_RS232.
The F81532/534 can be disable port by manufacturer with
following H/W design.
1: Connect DCD/DSR/CTS/RI pin to ground.
2: Connect RX pin to ground.

1: Read MSR.
2: Turn MCR LOOP bit on, off and read LSR after delay wit

The F81532/534 had 4 clocksource 1.846/18.46/14.77/24MHz and baud rates

The F81532/534 had 4 clocksource 1.846/18.46/14.77/24MHz and baud rates

side. This patch will force all TX data frame with delay 1bit gap.
