Subject: [PATCH v2 1/5] Documentation: DT: Renamed of-serial.txt to 8250.txt
The file of-serial.txt was only for 8250 compatible UART implementations,
so renamed it to 8250.txt to avoid confusing other persons.

+Optional properties:
+- current-speed : the current active speed of the UART.
+- reg-offset : offset to apply to the mapbase from the start of the registers.
+- reg-shift : quantity to shift the register offsets by.
+- reg-io-width : the size (in bytes) of the IO accesses that should be
+ performed on the device. There are some systems that require 32-bit
+ accesses to the UART (e.g. TI davinci).
+- used-by-rtas : set to indicate that the port is in use by the OpenFirmware
+ RTAS and should not be registered.
+- no-loopback-test: set to indicate that the port does not implements loopback
+ test mode
+- fifo-size: the fifo size of the UART.
+- auto-flow-control: one way to enable automatic flow control support. The
+ driver is allowed to detect support for the capability even without this
+ property.
+- has-hw-flow-control: the hardware has flow control capability.
